Converting HyperV Snapshots to Dumps

Brian Desmond — Tue, 02 Feb 2010 00:07:19 GMT

Microsoft has had a tool internally for a while that would convert a saved state or snapshot of a HyperV virtual machine into a dump that you could open with the Windows debugging tools. This is really pretty handy sometimes when troubleshooting. The good news is this tool is now publically available here.

BlackBerry Enterprise Server and Exchange Server 2010 Throttling Policies

Brian Desmond — Mon, 01 Feb 2010 02:28:27 GMT

One of the new features in Exchange Server 2010 is the concept of Client Throttling Policies. In summary, Client Throttling Policies are designed to limit the amount of system resources a given user can consume and in turn impact performance for other Exchange users. Out of the box there is a default throttling policy (use the Get-ThrottlingPolicy cmdlet) applied to all users:

As you can see, most of the valuesa re null, however each of the services has a *MaxCurrency property. These define the maximum number of connections a given user can have to that service. For example, the EASMaxConcurrency value limits a given user to a maximum of ten Exchange ActiveSync connections. Each of the values is documented in the Set-ThrottlingPolicy cmdlet documentation. Of particular note to this discussion is the RCAMaxConcurrency value which defines the maximum number of concurrent connections a given user can have to the RPC Client Access service. The RPC Client Access service is new in Exchange 2010 and it handles all MAPI connections to Exchange.

BlackBerry Enterprise Server (BES) uses a single service account to proxy all of the connections to Exchange on behalf of BlackBerry users. The side effect of this is that it’s quite likely that BES will need to have more than twenty (default limit) connections open to Exchange at a given time. If you review the documentation from RIM, they recommend setting the RCAMaxConcurrency value to null (equivalent to unlimited) for all users. This is really not a great idea at all.

Instead, what you can do is define a new Client Throttling Policy without an RCAMaxConcurrency value and apply it directly to the BES service account. The PowerShell script below does just that. The script assumes that your BES service account is called “BESAdmin”. If it isn’t modify the script accordingly.

New-ThrottlingPolicy "BES Throttling Policy" -RCAMaxConcurrency:$null
Set-Mailbox besadmin -ThrottlingPolicy "BES Throttling Policy"

You can easily confirm that the new policy is applied to the BESAdmin account by inspecting the properties of BESAdmin mailbox:

Get-Mailbox besadmin | fl Name,ThrottlingPolicy

You should see results similar to the following:

Name : BES Admin
ThrottlingPolicy : BES Throttling Policy

How to Create an ActiveSync Device Report

Brian Desmond — Sun, 31 Jan 2010 23:42:00 GMT

Exchange logs quite a bit of info about ActiveSync device partnerships and you can use this to create reports about the utilization of mobility features in your organization. Getting this data requires a couple of intermediate steps before you can export it to a CSV for processing in something like Excel (or another script). The PowerShell script below will export all of the ActiveSync device relationships in your organization. Keep in mind that this will include old relationships which are no longer active. Depending on how large your organization is and the number of device relationships out there, it may take a little while for the script to run.

Note: If you have a mixed version organization (e.g. Exchange 2007 and Exchange 2010), you’ll need to run the script twice. Once in the Exchange 2007 Management Shell and once in the Exchange 2010 Management Shell. The cmdlets used here are not backwards (or forward compatible). I’ve provided two versions of the script - one for Exchange 2007 and one for Exchange 2010.

Exchange 2007 Version

$devices = @()
$mailboxes = Get-CASMailbox -ResultSize:Unlimited | Where-Object {$_.HasActiveSyncDevicePartnership -eq $true -and $_.ExchangeVersion.ExchangeBuild -ilike "8*"}

foreach ($m in $mailboxes) 
{
	$devices += Get-ActiveSyncDeviceStatistics -Mailbox $m.Identity
}

$devices | Export-Csv DeviceStats.csv

Exchange 2010 Version

$devices = @()
$mailboxes = Get-CASMailbox -ResultSize:Unlimited | Where-Object {$_.HasActiveSyncDevicePartnership -eq $true -and $_.ExchangeVersion.ExchangeBuild -ilike "14*"}

foreach ($m in $mailboxes) 
{
	$devices += Get-ActiveSyncDeviceStatistics -Mailbox $m.Identity
}

$devices | Export-Csv DeviceStats.csv

You can open the exported CSV in Excel from here and generate reports based on that. There is quite a bit of information in the report including some personally identifiable information (PII) for the devices so keep that in mind before redistributing the raw data file.

Small Update to Redirection Blog

Brian Desmond — Sun, 31 Jan 2010 22:40:00 GMT

Last week, I posted about how to redirect HTTP connects to Exchange 2010 OWA to HTTPS. There was a small issue in the post which I’ve now corrected. If you explicitly disabled HTTP Redirection for the OWA virtual directory, you would break the /exchange, /public, and /exchweb virtual directories which redirect to /owa.

If you browse to https://owa.customer.com/exchange, you might see the following event in the Application log of your CAS server:

To resolve this, open the web.config file for OWA. The path is in the event. I highlighted it in red boldface font above so you know where to look. Inside of the web.config file, search for and remove this line:

<httpRedirect enabled="false" />

Warning: Improperly editing the web.config file for OWA could render it entirely inoperable. I highly recommend that you save a backup prior to making any changes to the file.

Redirecting OWA URLs in Exchange 2010

Brian Desmond — Sun, 17 Jan 2010 22:52:00 GMT

One of the things I’ve been doing for as long as I can remember is redirecting requests that don’t go to https://owa.customer.com/owa (or /exchange) to the correct URL. So, if someone goes to http://owa.customer.com or https://owa.customer.com, they get redirected to the correct (secure) URL. Historically I’ve always done this with two components:

A custom website listening on Port 80 on each CAS server
A default.aspx file in the root of the Default Web Site redirecting to /owa

This approach no longer works with Exchange 2010 CAS because the PowerShell virtual directory actually operates over Port 80 (authentication is Kerberized). If you try and tinker with this, you’ll start getting errors from Remote PowerShell like this:

VERBOSE: Connecting to cas01.customer.com
[cas01.customer.com] The WinRM service cannot process the request because the request needs to be sent to a different machine. Use the redirect information to send the request to a new machine. Redirect location reported: https://owa.customer.com/owa/PowerShell. To automatically connect to the redirected URI, verify "MaximumConnectionRedirectionCount" property of session preference variable "PSSessionOption" and use "AllowRedirection" parameter on the cmdlet.
+ CategoryInfo : OpenError: (System.Manageme....RemoteRunspace:RemoteRunspace) [], PSRemotingTransportRedirectException
+ FullyQualifiedErrorId : PSSessionOpenFailed

In order to work around this, you need to use the HTTP Redirection feature in IIS (the default.aspx trick mentioned above should work too), as well as remove the requirement for SSL at the top level Default Web Site object. You have to be careful doing this because when you set settings on the web site, IIS will push them down to any virtual directory below which does not explicitly set that setting itself. To setup the redirect, select the Default Web Site in IIS Manager, and open the HTTP Redirect option under IIS. Complete it like this:

Warning: It’s very important that you check the checkboxes exactly as shown in the screenshot above!

Once this step is complete, you need to remove the enforced redirect from each of the virtual directories under the Default Web Site. To do this, select each virtual directory individually, and then open the HTTP Redirect property and uncheck the “Redirect requests to this destination” checkbox. You’ll need to do this on the following virtual directories:

aspnet_client
Autodiscover
ecp
EWS
Microsoft-Server-ActiveSync
OAB
PowerShell
Rpc

Note: The Exchange, Exchweb, and Public virtual directories should redirect to /owa.

If at this point you simply browse to http://cas01.customer.com, you’ll get an HTTP 403.4 error. This is because SSL is required at the top-level website. In order to get the redirect working, we need to disable SSL for the toplevel website while leaving it enabled for the relevant child virtual directories.

Select the Default Web Site and open the SSL Settings properties. Uncheck the Require SSL checkbox as shown below:

Like the redirection settings, this change will be inherited down the tree for any virtual directory which does not explicitly set the setting independently. Ensure that SSL is required for the following virtual directories:

Autodiscover
ecp
EWS
Microsoft-Server-ActiveSync
OAB
owa
Rpc

Warning: If you require SSL for the PowerShell virtual directory, you will render Remote PowerShell inoperable!

Once you’ve configured the redirection and SSL settings, open a command prompt and run iisreset. At this point you should be able to browse to http://localhost on the CAS server and get redirected to https://owa.customer.com/owa. These steps were tested on Windows Server 2008 R2. While they should be similar under Windows Server 2008, they may not be identical.

McAfee EPO and NLB Clusters

Brian Desmond — Sun, 17 Jan 2010 21:31:21 GMT

I rolled out McAfee agents to about ten servers yesterday and four of them wouldn’t show up properly in the console. I did the usual troubleshooting with this, played with cmdagent, and didn’t really get far. What I did eventually notice is that while two of my machines would show up as Managed in the console, the other two simply refused. The wierd behavior here is that if I went in cmdagent and resent all the properties of the missing servers, suddenly the other two would disappear from the console. I did a bit of research and it appears that McAfee generates the client identifier based on the machine’s MAC Address.

This piece of information was the ticket here. The machines in question are in two Windows Network Load Balancing (NLB) clusters. The high level summary of how NLB works is that it shares a MAC address amongst all the machines in the cluster. McAfee was using this MAC to generate agent identifiers and was coming up with duplicates in both clusters. I did a bit of research and McAfee has an article in their knowledge base as to how to deal with this with a workaround.

When you go to create the registry value described in the article, McAfee prevents it because they’re hooking things and making sure you don’t touch their part of the registry. This is implemented in the Access Protection Policy for VirusScan. If you look at the VirusScan log, you’ll see a line like this and the corresponding regedit error:

1/17/2010 12:26:02 PM Blocked by Access Protection rule DOMAIN\bdesmond C:\Windows\regedit.exe \REGISTRY\MACHINE\SOFTWARE\Wow6432Node\Network Associates\ePolicy Orchestrator\New Value #1 Common Standard Protection:Prevent modification of McAfee Common Management Agent files and settings Action blocked : Create

To work around this, I edited my Access Protection policy and disabled blocking for the three “Prevent modification of McAfee files and settings” rules highlighted below:

2009 in Review

Brian Desmond — Tue, 29 Dec 2009 08:44:00 GMT

2009 has been pretty busy for me all things considered. I’ve been all over the place visiting with customers and doing conferences. I took a few minutes to add up a couple of spreadsheets and came up with some numbers:

Countries	9
US States	7 (plus District of Columbia)
US Cities Visited	32 (approx)
Airplanes	81
Miles Flown	150,882 (approx)
Hotels Visited	32 (approx)
Hotel Nights	135
Days on the Road	181

Already off to four states in the first couple weeks of the year and the conference schedule is starting to line up. Happy New Years!

Installing WinPcap Silently

Brian Desmond — Sun, 29 Nov 2009 03:06:17 GMT

A standard part of my server build I do everywhere is installing WireShark. WireShark of course requires WinPcap. While you can install WireShark silently, it conveniently doesn’t install WinPcap, rendering it useless. I used to work around this by installing NMap as part of the build since NMap does include WinPcap in its’ silent install. Unfortunately this seems to have broken under Windows Server 2008 R2.

The good news is you can work around this with the hackish but effective AutoIt. Below is my AutoIt script for installing WinPcap 4.1.1.

; ==========================================================================
; NAME: WinPcap AutoIt Installer
; 
; AUTHOR: Brian Desmond, brian@briandesmond.com

#RequireAdmin

Run("WinPcap_4_1_1.exe")
WinWaitActive("WinPcap 4.1.1 Setup")
Send("!n")
WinWaitActive("WinPcap 4.1.1 Setup", "Welcome to the WinPcap")
Send("!n")
WinWaitActive("WinPcap 4.1.1 Setup", "License Agreement")
Send("!a")
WinWaitActive("WinPcap 4.1.1 Setup", "Installation options")
ControlClick("WinPcap 4.1.1 Setup", "Installation options", "[CLASS:Button; INSTANCE:2]") ; hack to click the install button
WinWaitActive("WinPcap 4.1.1 Setup", "Completing the WinPcap")
Send("!f")

Note: This depends on the version number strings in the WinPcap setup. If it changes, you’ll need to tweak the script above accordingly.

I just compiled this to an EXE using the AutoIt compiler and it worked just fine.

Installing Dell Update Packages on Windows Server 2008 R2

Brian Desmond — Sun, 29 Nov 2009 02:41:51 GMT

Despite the release notes in the PE2950 2.6.1 BIOS, “Added support for the Microsoft(R) Windows Server(R) 2008 R2 operating system”, the install package doesn’t actually work properly. It has a prompt telling you that it’s running on an unsupported OS. This completely invalidates the silent install capability. This problem seems to extend to all the other install packages.

Fortunately, this is pretty easy to work around with the built in Application Compatibility settings in Windows. You just need to set the executable to the Windows Server 2008 (Service Pack 1) compatibility mode:

Since I’m running all these packages as part of an unattended build, I went ahead and set all of the packages to the WS08 SP1 compatibility mode on a test machine and then exported the registry key that has these settings. To do that, export HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers to DellCompat.reg. Next, you can run reg import DellCompat.reg and import the settings which will enable the packages to function correctly.

For reference, I put all of the update packages in C:\DellSrc. The batch file below imports the registry changes, installs all of the latest (as of 28-Nov-2009) drivers and firmware for a Dell PowerEdge 2950 running Windows Server 2008 R2, and installs OpenManage Server Administrator 6.1.

reg import c:\dellsrc\DellCompat.reg
c:\dellsrc\PE2950_BIOS_WIN_2.6.1.EXE /s
c:\dellsrc\BMC_FRMW_WIN_R202152.EXE /s
c:\dellsrc\ESM_FRMW_WIN_R149431.EXE /s
c:\dellsrc\RAID_FRMW_WIN_R216024.EXE /s
c:\dellsrc\RAC_FRMW_WIN_R209365.EXE /s

start /wait msiexec /i c:\dellsrc\openmanage\SysMgmt.msi ADDLOCAL=BRCM,INTEL,IWS,OMSM,RAC5,SA /qb

Here is the DellCompat.reg registry script:

Remotely Configuring DRAC Cards

Brian Desmond — Wed, 25 Nov 2009 22:48:00 GMT

The two scripts below are a quick solution to pushing out an identical (except for IP and hostname) configuration to a large number of Dell DRAC boards. They’re not the most efficient and they were written for a specific scenario, but, they should be easy enough to customize. There are two scripts:

RemoteDracConfig.vbs – This one will take a config template, customize it for a host, and apply it via psexec
RemoteDracConfigLoop.vbs – This one will read an input CSV and call RemoteDracConfig.vbs for each line

I seperated the scripts specifically so that the first one could easily be used as part of a build process without having to generate an input file for it. To get started, you’ll need to configure a reference DRAC and export its configuration. Once you’ve done the configuration work, run racadm getconfig –f baseline.txt on the reference machine. You’ll next need to replace the machine specific info with tokens. I support two:

%drac-ip% – this one will get replaced with the IP to use for the DRAC
%drac-hostname% – this one will get replaced with the hostname to use for the DRAC

Note: This script assumes that the drac-hostname will actually be the server’s hostname with something appended on the end. For example all my DRACs I’m using server-drac.domain.com as the FQDN, so, the relevant lines in my DRAC config look like this:

cfgDNSRacName=%drac-hostname%-drac
cfgDNSDomainName=domain.com

If you want to do something different, you’ll need to modify the script.

The baseline config also will not have any passwords in it. You’ll need to scroll down to the cfgUserAdmin section and uncomment the # cfgUserAdminPassword=******** (Write-Only) line and replace it with cfgUserAdminPassword=YourPassword. You’ll also need a copy of psexec from Sysinternals. The path to that is hardcoded at the top of RemoteDracConfig.vbs. You’ll need to change this.

Here is RemoteDracConfig.vbs:

I tested this against several Windows Server 2008 x64 and Windows Server 2008 R2 machines equipped with DRAC5 boards and it worked well. YMMV of course. The racadm tool ships with the Dell OpenManage Server Administrator components so you’ll need those installed on each machine in order for this to work.
