Windows Server - Question - Intersite Messaging

Asked By Sabo, Eric on 02-Apr-08 10:10 PM
If I am at Windows 2003 Service Pack 2 and my forest level is at windows
2003 native.   Can I disable the "Intersite Messaging" service?    All
domain controllers are not running SMTP service so I am assuming this
service is not needed in my domain.

Thanks in advance,
Eric Sabo

When the forest has a functional level of Windows Server 2003, the KCC does
not use Intersite Messaging for calculating the topology. However,
regardless of forest functional level, Intersite Messaging is still required
for SMTP replication, DFS, universal group membership caching, and Net Logon
automatic site coverage calculations. Therefore, if any of these features
are in use, do not stop Intersite Messaging.
