Use of UPN Suffix in windows 2003?

noreply@blogger.com (virtual guru) — Thu, 16 Jun 2011 17:15:00 +0000

Suppose you have a company domain as microsoftsccm.com, as users when they log in they many feel the domain name is too long, so we as administrator can set up Alternative UPN

(user principle name), upn-suffix which is set:

We need to go to AD domains and trusts àright click on AD domains and trusts node-àproperties -à and add UPN suffix as micro.com, so now users can log with this micro.com also.

Now you need to go to each users or select all bunch of users, go to there properties àaccounts tab and select UPN suffix and select micro.com

Upn suffix(user principle name): can just be used by admins for users to log on easily or it can also be a DNS domain name.

Stateful packet inspection means that the firewall will see the TCP conversation

Private IP address

Windows server 2003 Printer Tutorial

noreply@blogger.com (virtual guru) — Fri, 10 Jun 2011 15:09:00 +0000

Printer---software device

Printer device—hardware device

Local printer: attached directly to a computer

Network printer: connected to a HUB or switch

The print drivers are installed on a print server and are shared.

Printer priority: 99 highest, ex: if we have 2 printers make the priority for one printer as 10 and the other one 5. So the higher priority will print first, same for the print schedule

Separator page: Create a separator page and which separates bundle of pages, ex: when you want to print 100 pages, but 50/50 should be separated, so once 50 pages are printed out, you will receive a separator page.

We can open the print server using a web browser, but, u need to have IIS installed. On the print server

From the client machine, http: // izone/printer

When we configure a local printer we can select ports as LPT1 etc, but, when we need to configure a network printer then we need to add tcp/ip port

Group policy—computer settings—printer settings—pre-populate printers in AD

When every any user search for printer they are already pre-populated in AD

Exchange server 2007 message flow

noreply@blogger.com (virtual guru) — Sun, 22 May 2011 19:40:00 +0000

Message transport components:

Submission queue: stores all messages on disk awaiting processing

Store driver: received messages from outbox, when ever we send mails they are stored in outbox

Ms Exchange mail submission service

Runs on mail box server

Notifies hub transport when MSG is ready to be retrieved from senders outbox

Stores driver picks up the message

Pick up directory

Submits messages to submission queue

Categorizer:

Process messages from submission queue

Handles messages with multiple recipients

Determines routing path

Applies organization message policies

Message flow from outside the organization:

Enters via SMTP receive connector

Edge server or hub server

Message is dropped into submission queue

Message flow from with in organization

Enter via SMTP receive connector

Hub transport server

Pickup directory

Store driver dropping then into the submission queue

SCC: single copy cluster

noreply@blogger.com (virtual guru) — Sun, 22 May 2011 19:31:00 +0000

Clustering technology, similar to earlier exchange versions.

Preparing Active Directory for SMS 2003

noreply@blogger.com (virtual guru) — Mon, 25 Apr 2011 19:59:00 +0000

First we need to ensure that the user we have logged in should have schema admin rights.

Go to AD and add a user who need to be schema admin

Insert the SMS 2003 CD in the drive and go to CMD

>cd smssetup\bin\i386 –then enter

>extadsc.exe –enter

The scheme will be modified.

To check if AD schema was extended properly, go to C drive and check for extadsc file.

To map network drives from command line

noreply@blogger.com (virtual guru) — Thu, 03 Mar 2011 18:55:00 +0000

Share a folder on file server or any server and open notepad and type

Net use x: \\server1\sales

Net use y: \\server1\HR

And save this file as .bat

the sales and HR folder should be created upfront and then be shared.

So how can you apply this to users.You just need to go to GPMC create a GPO and edit the user settings -- windows settings--scripts and add the batch file create into this scripts. Point to remember : the .bat file should be saved in LOGON folder on SYSVOL folder.

when a user logs on to the computer he or she will receive the respective drives shared and they can save data. the main advantage is that they will never loss there data as the info is saved centrally on another server and they can access this from any client machine they log into.

LDAP ATTRIBUTES

To view IP settings in a text file

noreply@blogger.com (virtual guru) — Wed, 02 Mar 2011 10:42:00 +0000

Normally we all check the IP configurations by going to CMD and IPCONFIG /ALL.

Now to save this into a text file.

c:\>ipconfig \all > c:\config.txt
c:\>ipconfig \all > d:\config.txt

How to get a computers IP address?

noreply@blogger.com (virtual guru) — Tue, 01 Mar 2011 18:19:00 +0000

1. Go to to CMD:
ipconfig /all

2.

Ping to the client machine

Ex: ping client22

Now the ip address and MAC address are cached.

To view the cache

Arp –a

We can also use:

Cmd

Getmac /s client22

Define Multi homed server?

noreply@blogger.com (virtual guru) — Tue, 01 Mar 2011 18:15:00 +0000

Server with 2 or more NIC cards.

DHCP Super scope

noreply@blogger.com (virtual guru) — Tue, 01 Mar 2011 18:08:00 +0000

Combination of 2 scopes. Ex: 192.168.1.1 and 192.168.2.1

We combine these 2 to lease out the ipaddress no matter the network ID

One client can get 192.168.1.1 and another client can get 192.168.2.1

So now when client A wants to talk to client B. they can’t communicate as the network ID’s differ. Now we need to install RRAS on DHCP server.

In a scenario like this we need to have the default gateway as ipaddress of DHCP server.
