Error
While publishing a website redirection rule I found an error as below
"To use the redirect option ,you must provide a Webserver name"

Solution
This is because there is no specific entry in Action tab for http/https protocol in the web publising rule for redirection

Lync Calls Failing with error code0x12b

2013-03-28T01:34:00.003-07:00

Issue :

ms-client-diagnostics: 22; reason="Call failed to establish due to a media connectivity failure when both endpoints are internal";CallerMediaDebug="audio:ICEWarn=0x12b,LocalSite=

Cause

This might be because of internal VLAN restrictions implemented. Because of those rules, Users are not able to contact the VoIP device .

Resolution :

Check there is no restrictions implemented between the user VLAN and the VoIP devices. If that could not be changed, check the MRAS server internal IP address is reachable from both the VoIP device and the user system

Lync Conferencing Announcement management With Powershell

2012-12-14T03:34:00.005-08:00

Lync Conferencing Announcement management With Powershell

As mentioned in the Technet article

http://technet.microsoft.com/en-us/library/gg398834.aspx below o

the output of the

Get-CsDialinConferencingConfiguration command is

Identity : Global

EntryExitAnnouncementsType : ToneOnly

EnableNameRecording : True

EntryExitAnnouncementsEnabledByDefault : False

EnableNameRecording :Determines whether anonymous participants are asked to record their name before entering the conference. The default value is "$true," which means that anonymous participants are prompted to state their name when joining a conference. (Authenticated participants do not record their name because their display name is used instead.)

EntryExitAnnouncementsEnabledByDefault : Indicates whether announcements are turned on or off by default. The default value is "$false," which means that by default there are no announcements when participants join or leave a conference. The meeting organizer can override this setting when scheduling a meeting.

EntryExitAnnouncementsType : Indicates the action taken whenever a participant joins or leaves a conference for which announcements are enabled. The default value is "UseNames," which means there is an announcement similar to the following: "Ken Myer has joined the conference" when announcements are turned on.

Set-CsDialInConferencingConfiguration -EnableNameRecording $True -EntryExitAnnouncementsType "ToneOnly"

The only other option is "UseName" here the entry/exit announcement will be with the user name

Get-CsDialInConferencingConfiguration -Filter "site:*" | Set-CsDialInConferencingConfiguration -EnableNameRecording $True

There we can put the different site name by replacing the * accordingly.

Get-CsDialInConferencingConfiguration | Set-CsDialInConferencingConfiguration -EntryExitAnnouncementsEnabledByDefault $false

Most useful Powershell Commands for Exchange

2012-12-12T05:13:00.000-08:00

To track emails whether it is delivered or not

1) Get-MessageTrackingLog -Recipients yourmailid@yourdomain.com -sender mailID2@xyz.com | fl *time*,*subject*

If you want to input the sender and recipient you can use the below command
2) Get-MessageTrackingLog -sender (read-host "Sender") -Recipients (read-host "Recepient")| fl *time*,*subject*

Atleast Sender name or recipient name anyone should be there to get the result. If you want to get all Senders or all recipient don’t give any inputs just hit enter in the prompt

3) Get the list of SMTP addresses
Get-Mailbox -ResultSize Unlimited |Select-Object DisplayName,ServerName,PrimarySmtpAddress, @{Name=“EmailAddresses”;Expression={$_.EmailAddresses |Where-Object {$_.PrefixString -ceq “smtp”} | ForEach-Object {$_.SmtpAddress}}} |Export-csv Addresslist.csv
This will generate the list of all user details with their primary and secondary SMTP address and import to a csv file

4) get the list of Active Directory users who haven’t updated their Phone numbers

get-user -resultsize Unlimited |Where {$_.mobilePhone.length -lt 8 -and $_.Phone.length -lt 8 -and $_.SamaccountName -like "U*"} |select Name,SamaccountName,MobilePhone,Phone |export-csv E:\MissingNumbers.csv –NoTypeInformation

5) Get the List of all email address of users to a powershell.
This script can also used to get the complete list of secondary email addressess or to export Primary and secondary email IDs to csv

Error While exporting Dbimpexp.exe in Lync

2012-11-27T10:15:00.000-08:00

While exporting contact list using DBimpexp.exe an error occurs like below

SQL Schema Version: 59

User Data Schema Version : 21

Exporting 8037 Homed Resource(s) from database...

Error: '', hexadecimal value 0x1A, is an invalid character.

Issue :

The exporting of Lync contact list was failing after 80% of completion. So Dbimpexp.exe was not working hence no contact list backup as such. We were completely relay on DB backup but the contact list backup is very critical to re-push the individual contact list for the users if any failure happened. We were getting a 300+ MB file which was having details till approximately 80% of user details.

Cause :

This is because there is a chance of an extra junk character entered into the contract list of a user or more. But to identify which user was having the issue is a complicated thing.

Resolution:

Step 1 :

Get the list of all sip enabled users using Lync management shell

I took the list of all users who have enabled for sip by the below command in Powershell

Get-CsAdUser |fl Sipaddress >> emailIDs.txt and get the list of Sip enabled users to a notepad. Using excel tricks I have removes the string sip: .

eg: sip:user1@mydomain.com to user1.mydomain.com and also I have removed unwanted space as well.

Note: You can use the command get-csuser |FL windowsemailAddress if sip URI is same as email address.

Step 2:

copy dbimpexp.exe from

C:\Program Files\Common Files\Microsoft Lync Server 2010\Support

(Path may change as per your configuration) and put it in a new folder. Copy emailIDs.txt file which we have previously generated also to the same folder .

Create a batch file with a friendly name (Me it is Backup.bat) and save it in the same folder.

Content of the Batch file is as below :

FOR /F %%i in (emailIDs.txt) do (

DBIMPEXP.EXE /hrxmlfile:UserListFolder\%%i.xml /sqlserver:YourSQLserver.yourdomain.com /user:%%i >>CommandOutput.txt

echo %%i >>output.txt

)

This batch file will take each user from emailIDs.txt file and do an individual contact backup and put the output into a new folder named userListFolder with the username.xml format .This also append the output of the command prompt to a file named CommandOutput.txt .When ever the loop takes a user it will append the command line and then it will also append the username next to it.

By that we will get the exact user details who created the issue

Sample CommandOutput.txt file is given below

……………………………………

…………………………………..

Export completed successfully.

User100@mydomain.com

SQL Schema Version: 59

User Data Schema Version : 21

Exporting 1 Homed Resource(s) from database...

100% complete.

Export completed successfully.

User102@mydomain.com

SQL Schema Version: 59

User Data Schema Version : 21

Exporting 1 Homed Resource(s) from database...

100% complete.

Export completed successfully.

User103@mydomain.com

SQL Schema Version: 59

User Data Schema Version : 21

Exporting 8037 Homed Resource(s) from database...

Error: '', hexadecimal value 0x1A, is an invalid character.

User104@mydomain.com

SQL Schema Version: 59

User Data Schema Version : 21

Exporting 1 Homed Resource(s) from database...

100% complete.

Export completed successfully.

User105@mydomain.com

So in this case User104 was creating issues.

Step 3

Now open ADSIedit and get the details on this user.and check any inappropriate details as there in all fields.

If you couldn’t find any issues,open LDP and then connect to the same computer .

Open the user who is having the issue and copy the details to the notepad .

Save the file with the name Baduser.txt.

Open a normal user who have successfully exported and copy its details aswell.

Paste it to a new notepad and save with the name GoodUser.txt.

Download any file compare software and compare gooduser.txt and baduser.txt.

(I use Beyond Compare software ,trial version is enough for one time use)

While comparing 2 files which I got from ldp ,I found the street address of the user whose backup was failing ,was having an entry like

streetAddress: <ldp: Binary blob 84 bytes>;

After opening the Street address details in ADSIEdit,I found there is a Junk Character like [-> ] which was causing the issue.I changed the same and Done !!!!!.the backup completed successfully.

OCS Addressbook error (Resolved)

2012-08-27T02:24:00.000-07:00

While expanding a distribution list OCS user recieve the below error

Error 1

Cannot synchronize with the corporate address book. This may be because the proxy server setting in your web browser does not allow access to the address book. If the problem persists, contact your system administrator.

Error 2

Distribution group service could not perform this action .Contact system administrator to investigate this problem.

Case study :

The issue happened because of the internal certificate which is renewed.

I took the configuration information of the MOC client and took the internal Url entry

Eg. Internal From Server :https://ocspool.mydomain.com.com/Abs/Int/Handler.

While browsing this URL I found it was not opening. Then checked the IIS in one frontend server and checked the certificate associated to that (edit bindings-option) Select new certificate and clicked OK.

And Issue is resolved :)

-----------------------
One solution as below

Solution :

The first part of errors mainly due to the SQL server connectivity and second part is with the compatibility issue

. Check the SQL server whether named pipe and TCP/IP configuration have enabled or not. Also check whether the required ports are enabled on the SQL server firewall, you will be able to solve the first part.

Install the service pack of SQL 2008 to rectify the second issue

An error occurred during the pool backend detection: Pool backend discovery failed. Failed to start SQL service or invalid SQL instance (Solved)

2012-03-13T05:02:00.001-07:00

)Issue

When you try to create an enterprise pool by using the Microsoft Lync Server 2010 or Microsoft Office Communications Server deployment wizard, you receive the following error message:

"An error occurred during the pool backend detection

Pool backend discovery failed

Failed to start SQL service or invalid SQL instance.

This can happen due to network or credential problems. Please make sure networks is good and logon has sufficient permissions."

Solution

· Task 1

In the FE configuration wizard ,in SQL Server instance box try to use FQDN rather than its netbios name

Eg: MYSQLSERVER.mydomain.com\OCSINSTANCE

If OCS is using default instance do the change accordingly

· Task-2

Check the DNS in the AD whether OCS Pool name is added or not

· Task 3

Check the windows firewall is configured properly so that it wont stop any communication between OCS front end server and SQL backend servers .Preferably stop the firewall and check first , if it is working fine then try to add the relevant rules for security standpoint

· Task 4

Check whether SQL server, SQL browser and SQL agent services are running in the SQL server. If this is a freshly installed SQL server, try to open the SQL management studio and connect to the SQL DB to check it is working fine.

· Task 4

Install the latest service pack for the installed SQL version and reboot the server

· Task 5

Check whether the user is having sufficient privilege in both SQL and OCS (for OCS the user must be a member of RTCUniversalServerAdmins group) and in SQL user preferably should be in sysadmin group (I am not sure whether any other privilege is sufficient or not )

· Task -6

Check whether the SQL server is configured to accept remote connections.

o Click Start, Programs, Microsoft SQL Server 2005/2008 and select SQL Server Configuration Manager.

o Select “SQL Server Network Configuration “

o Double click on “Protocols for SQLEXPRESS”

o Check whether TCP/IP is enabled or not, if not enabled and select Yes to enable it .

o In the next tab “ IP address “,check whether the port number is same for all the TCP port field, (default port is 1433) and change accordingly ,for me it is 1433 itself for all .

o Check whether IP address of the SQLserver is added into the IP address field under IPA2 heading.

o Restart the SQL server services from services.msc and

· Task -7

Click “Retry “option in the FE server.

communicator cannot connect to the server because the required security is not in place (Solved)

2012-03-12T00:16:00.000-07:00

OCS client is not able to expand users in any of the AD group lists . It is showing error as below

“Communicator cannot connect to the server because the required security is not in place”

Solution:

The issue was with the certificate which is not providing a secure channel between the user computer and the server

I tries the below links from the user system and found it was showing a certificate error

https://ocspool.yourdomain.com/abs/int/files/Sample_Company_Phone_Number_Normalization_Rules.txt
https://ocspool.yourdomain.com/conf/ext/Tshoot.html

Note: where ocspool.yourdomain.com is the FQDN of the OCS pool

Then I installed the certificate from the IE itself and the issue resolved

Desktop Share Icon not in OCS and Lync client (Solved)

2012-03-05T23:18:00.007-08:00

desktop sharing icon not in MOC
OR
Desktop share option is not in OCS

I was installing OCS and Lync in the same domain for testing purpose. After installing the complete infrastructure I realized that “Desktop Sharing “option was not available on both OCS and Lync clients. It was disappeared in the client window L . After googling for some time I realized that it is because “Global policy “was not configured yet on both OCS and Lync
Enable Desktop share in OCS
To enable this open OCS R2 administration console, select Global Properties, Meetings tab, locate Default Policy (under Policy Definition) and click Edit. Check “Enable Program and Desktop Sharing” and “Allow control of shared programs and desktop”
For anonymous desktop sharing use, select “Allow users to invite anonymous participants” within the OCS global properties

Enable Desktop share in Lync

Open “Lync server Control panel” and select “Conferencing “in the left side pane. Edit “Global” settings. And select “enable Application sharing “ and Enable Application sharing and Desktop “

After these settings preferably do a service restart which will enable “Desktop Share” window in the clients communicator client

Prerequisite installation failed: Wmf2008R2 (Solved)

2012-03-04T23:24:00.000-08:00

Error

Prerequisite installation failed: Wmf2008R2 is the error while I tried to install “Setup or remove Lync Components”

Cause

This error is due to the prerequisite check for the Media-Format-Package and returns the following information back to the Setup Lync Server components page: And the installation file couldn’t find the 2008R2 version of Windows Media Format.

Resolution

Open the server manager and open features and check whether “Desktop experience “option is selected or not. If not, check the box and install it.

Note: This installation requires a reboot

How to broadcast message using OCS (Solved)

2012-02-29T00:25:00.000-08:00

Broadcast your message in OCS

OCS supports command line application which will broadcasting messages to all users who were logged into OCS infrastructure . Sometimes administrator needs to warn users about upcoming outage or any incident throughout the organization and this is an easiest way of doing it. The user who needs to sends the broadcast should be a member of RTCUniversalServerAdmins group and preferably the admin user should logged into any of the FE server for better performance.

Step 1.

Login into any of the FE server and search for lcscmd.exe on it. It will be in the installation folder of Office communications software, or else you will get it in the installation CD of OCS server.

Step 2.

Open command prompt and change the directory where you have located lcscmd.exe

For me it is

C:\Users\administrator.UST\Desktop\OCS 2007 R2 X64 Ent Edition Server\2007R2\64BIT\Setup\amd64>

Because I have a copy of the installation files in my desktop

Step 3.

Type the below command and hit enter

LCScmd /Server /Action:BroadcastMessage /Role:SE Message:"Type here your message"

/Role:SE indicates it is for Standard edition installation and replace with /Role:EE for enterprise users.

Note: in my EE installation I even run /Role:SE without any issue (so seems this change is optional)

Done !!!!!! :)

All users who logged in will get the message from noreply@yourdomain.com .

The output of the command clearly denotes whether the command run successfully,how many users received this message, how many failed and also a log file will also generate on the %temp% folder which will completely describe the command execution flow including the error logs

How to get communicator chat or conference logs

2012-02-14T03:01:00.000-08:00

Get communicator chat logs from Achieving server

Previously OCS administrators were not confident enough to get Old chat logs because it requires more complex SQL queries to get chat logs exported from OCS Achieving server .Now MS released a new tool "OCSArchiveViewerSetup" which is having a GUI to retrieve the chat logs easily.

In the achieving and monitoring server install OCS Achieving tool "OCSArchiveViewerSetup". This is a free tool and the installation doesn’t cause any service interruption (as I experienced) .It can be downloaded from microsoft (just google it )..After installation it will ask for database to locate .Add the server name and instance name (ServerName/Instance) if default installation no need to specify instance name, and click Connect.

Put the complete sip Uri of the user to get the chat log. There is an option to select the time limit to get more refined chat logs .The tool is having an option to export the chat logs to IE too.

Join to Windows domain without connecting Domain server

2012-02-02T03:57:00.000-08:00

Join to Windows domain without connecting Domain server

With Windows 7 and Windows Server 2008 R2, that process gets a bit shorter with the release of Microsoft's Offline Domain Join tool djoin.exe. This tool enables Windows 7 or Windows Server 2008 R2 computers to join a domain without needing to communicate with a domain controller (at least, at first). Exceptionally useful for massive desktop rollouts, this tool comes in particularly handy when automating the deployment of virtual desktops. Here's how you'll use it:

Step one requires the use of a domain-joined computer. This computer, which will be referred to as the provisioning computer, works with a domain controller to pre-populate information about the offline computer. From the provisioning computer, run the following command to create the necessary provisioning file:

djoin /provision /domain <domainName> /machine <offlineMachineName> /machineou <TargetOuToCreateAccount> /savefile <fileNameWithTxtExtension>

Running this command creates a text file that includes the necessary information for later adding this computer to the domain.

Step two involves copying the file you created in step one to the client computer, which has not been joined to the domain.

Step three completes the process by ingesting the information in the copied file into the offline client. This is done by running the following command on the offline client computer:

djoin /requestODJ /loadfile <fileNameWithTxtExtension> /windowspath %SystemRoot% /localos

Once complete here, reboot the computer to join it to the domain. You can further automate this process by adding a little scripting around the domain join steps, or even including its information in an unattend.xml file.
