Exchange won't work after IIS install.

Posted on 2004-08-16
Last Modified: 2008-03-17
I reinstalled IIS because the WWW service was hanging on startup. This fixed the hanging problem, however, POP3 and SMTP no longer works with exchange (exchange in general seems to be down). Instant messaging is also down.

When try to start the Exchange POP3 service manually, it says "Error 1083: The executable program that this service is configured to run does not implement the serice."

What can I do to fix this? Please help, this is extremely urgent.

IIS and Exchange are very closely tied. You cannot touch IIS without upsetting Exchange.
Quickest solution is to put the Exchange CD in to the server and choose the reinstall option. This will leave all data and configuration in place, but will fix the server configuration.

I have SBS 2000 running, there is no seperate CD. I can't really find a Reinstall option for Exchange alone. Would uninstalling/installing have the same effect or would I lose the data and settings? Or is there a way to reinstall Exchange from the SBS CDs?

steps to follow in brief

1.Reapply the latest Windows 2000 service pack.
2. Reinstall Exchange. Reinstalling Exchange replaces any missing files without affecting the settings on the Exchange server.
3. Reapply any Exchange service packs and any other Exchange-related program updates

Reinstalled exchange, I can send email. However, Outlook cannot retrieve messages, and Instant Messaging is still down.

Any suggestions?

The problem is that Exchange is recieving emails, but the Outlook clients can't retrieve them. In fact, it seems like there is a problem with Outlook communicating with Exchange.

Have you tried OWA? http://<servername>/exchange

What has changed? IP address - any other settings?

OWA logs in, but doesn't retrieve emails too. You can see the emails in the list, but when you click on the actual email, it comes up with a "HTTP/1.0 500 Internal Server Error"
