ExportServers.vbs


This script connects to Active Directory and writes all the servers that are running Microsoft Windows Server 2003 to a text file; the next script uses this information as an input to create a computer rule element in ISA Server 2004.

 '==================================================================== ' ' PURPOSE: Add all the Computers running Windows Server 2003 from ' Active Directory to a text file called c:\ExportedServers.txt ' ' NAME: ExportServers.vbs ' ' RUN: cscript ExportServers.vbs <Domain Controller> ' ' WHERE: Run on a domain member of Active Directory as an administrator 'of the local computer, which must be Windows Server 2003. ' ' COMMENT: The script will only return Windows Server 2003 computers. '          This script was written by Jesper Hanno Hansen.

Note 

This function can also be performed using one of the ds commands included with Windows Server 2003. This will take one line rather than 211. From a command line, type dsquery * -filter "(&(objectCategory=computer)(operatingSystem=Windows Server 2003)) -attr name - l >c:\ExportedServers.txt.
