AFAIK you can optionally use AD to help your TSM clients resolve name of TSM 
Server.
As you ask the question below I must asume you do not use this feature, 
so you have to take care about your OPT files - to point to correct TSM server 
name or IP address.

Btw. I do NOT join TSM Server into AD, 
because I believe it is more simple 
if TSM server is as much stand-alone as possible 
in case of disaster recovery of whole computing center.
