I read this article http://support.microsoft.com/kb/153119. My questions:
1. How does each command can help me find out the problems?
2. and to telnet, I need to find out the exchange server fqdn or ip address, but it seems I cannot just telnet abc.com as sometime the exchange server not in the same location as exchange server. How can i find out the location of exchange server?
