I have a windows 2000 server running windows 2000 exchange sp3. Up till yesterday morning it was working fine now its not and nothing has changed on the server as far as i can see.
Any mail sent in from outside goes into the domain.local (local delivery) queue and does not get delivered to the users. Internal mail seems to be working ok except it appears to be much slower to deliver than usual. Mail sent from within the domain to outside just does not arrive.
What i have done.
2. Restarted the server
3. Stopped GFI Mail Essentials and AV software / services
4. Phoned microsoft and hung up when they told me it would be £200 to talk to a tech support
5. Panicked again
6. Installed all the available exchange updates
I just dont get it, 24 hours ago it was fine, nothing has changed on the server since then.
If anyone can save me £200 ms bill and more panicking i would be for ever grateful!
