Please help. I had to reinstall Exchange 2000 today.

After doing that and running the service pack, the IMAP and POP3 services have red "X"s on them.

When I try to manually start them I get an error message, and tells me to check the Event viewer. The warning at the event view says:

"An error occurred while starting the Microsoft Exchange POP3 Service: server instance number 1 failed to start with error 0x800cc801. "

Furthermore, no one can relay through our SMTP service.

Please help, this is very important.

I am not sure if this is your answer, but it is worth a shot. Technet article Q292522 says that "This issue may occur if you have Norton Antivirus 2000 (or 2001) installed on the computer and the Norton Email Protection application process, Poproxy.exe, is running. This should not be running on an Exchange server as it is a client component."

It did have a good idea to try; try to Telnet on port 110 to the Exchange server, and see if the header you receive identifies it as an Exchange POP3 port. If not, then Norton is answering and that is why you are having this error.

Here is the article URL:

hope this helps.
