I have a network that I recently upgraded from a 2000 mixed mode to a 2003 mixed mode (still have one win 2000 DC).
Before upgrading, I ran into something somewhere that recommended upgrading exchange first. However, that was after upgrading the DC's (actually replacing them altoghether).
Now the problem is that I have exchange failing all over the place. The machine tells the user it is trying to connect and never gets there. in the meantime, the que on exchange fills to the max amount of connections for that user and displays the error "could not communicate with exchange server".
There are two things that may be possible in causing this. They are:
1) Possible that the exchange is freaking out over the new DC's? If so, do I have to upgrade the exchange now? Is there any adjustment I can make to help this.
2)The machine keeps trying to connect to a machine that we had once aimed at making an exchange peer. I'm not sure how far my coworkers took this, but it is not running exchange. The problem is other machines think it is. When I try to kill the record of this machine, it re-propagates throughout AD.
Like I said, I don't know what the problem is. I only know my ass and job are on the line here and I'm already starting to dust off the old resume. Please help. Thank you much -- MW
