How to add the Exchange Tabs and Tasks to the Active Directory Users and Computers snap-in without loading Exchange System Manager

Requirements

Need access to the Adminpak.msi located on the Windows 2003 Server CD-ROM in the …\i386 directory. You can also download from www.microsoft.com/downloads.
Access to the …\Exchsrvr\bin directory on your Exchange 2003 Server.

Procedure

Open a command prompt
Change to the directory where the adminpak.msi file is located
Enter the following command: “msiexec /i adminpak.msi ADDLOCAL=FeADMgmtConsole /qb“ This will load the ADU&C tool along with DNS, AD Sites and Services and AD Domains & TrustReference article “http://support.microsoft.com/?kbid=314978” for detailed instructions on how to use this command.
(Note: I would recommend using a GPO to restirct access to the DNS, ADS&S and ADD&T tools to prevent your helpdesk from using these tools.) The install also creates a MSC called Active Directory Management located in the Administrative Tools folder which you may want to delete. The install WILL NOT create a shortcut to the ADU&C, ADS&S, ADD&T or DNS tools in your Administrative Tools directory…you’ll have to create them on your own. The install will only load the snap-ins.
Copy the following DLLs from your Exchange 2003 server (Default location: C:\Program Files\ExchSrvr\Bin) to your local c:\windows\system32 directory address.dll
escprint.dll
exchmem.dll
gblname.dll
maildsmx.dll
pttrace.dll
Open a command promt (or use the one from Step 1)
Change to the c:\windows\system32 directory
Enter the command: regsvr32 maildsmx.dll
That’s it.

Now you can create a custom MMC with only the ADU&C snap-in. This snap-in will have full access to the Exchange Tabs and Tasks with a minimal footprint on the client. One who is so inclined could even package it up as an MSI and publish it to their helpdesk staff via a GPO.
