I'm not sure if this helps but try article 828731. We are running exchange 2000 on a win 2k server in a 2003 AD. After the update we could receive e-mail but could not send any to the outside world. I had to call Microsoft support because we could not figure out what was causing this.
The microsoft tech had me run workaround #2. Then stop and start dns on your dc. You have to run this on all your dns servers. On the exchange side you have to flush then register dns. I am not sure if this will work on w2k3 and an e2k3. ----- Original Message ----- From: Matt Plahtinsky <[EMAIL PROTECTED]> Date: Friday, January 14, 2005 3:04 pm Subject: SMTP Problems > W2k3 E2k3 one Exchange server setup > > Started having some weird problems today.
