I'm baffled but pretty sure what I did caused the problem. I had SBS2000
configured with ISA using two network adapters. Everything was working
fine. I reconfigured the Internet to just go through a firewall/router on
the network. I disabled ISA, disconnected the second network adapter, and
configured the server to use the Internet through the single network adapter
connected to a router, etc. I then reconfigured the clients and everything
seemed to be running fine. Outlook users get their e-mails, all can access
the internet, VPN works fine, etc. I just noticed a problem with a user who
was using a phone/pda device which was pulling their e-mails from the server
through POP3 service. Ever since I made this switch, I cannot connect to
the server using POP3 in Outlook Express, etc. I get the following error:
The server xxxxxxx unexpectedly disconnected. error code 0x800CCC90 No
error messsage. When I try to telnet to the server through port 110, it is
immediately disconnected. I can telnet through port 143 and 25. Any
suggestions would be greatly appreciated. Sorry for the long post.
