Pop3 server not found

[Shane Huston]

I have one user (in an office of 5 users) who very
frequently throughout the day receives a "Pop3 Server not
found error". Her machine is running Win2k Pro SP4, Office
2000 and IE6 with all the updates. I rebuilt the machine
after slicking the hard drive just a few days ago. I've
confirmed the local ISP's DNS addresses and also that she
has them through DHCP in her TCP ipconfig. She's
configured as Internet Email with a .PST file on the saved
on the local server. Frequently, I can get it receiving
mail again by closing Outlook and then making sure the
MAPISP32.exe file shuts down. Sometimes MAPISP32 doesn't
shut down and I close it using the Task Manager. After
shutting down MAPI and restarting Outlook, Outlook then
starts receiving email again. Thanks for any assistance.

If you move the PST file to her hard drive (with Outlook closed), re-open
it, direct Outlook to the new location for the PST, does the problem recur?

Note that MS doesn't recommend or support accessing PST files across LAN/WAN
connections - you will likely have performance problems and perhaps even
data corruption.

I tried your suggestion, I still got the POP3 error.
However, when I initially open Outlook, I hit the
Send/Receive button immediately and got the POP3 error.

After Closing Outlook down, I restarted it and let it do
the first Send/Receive on its own. It worked as
advertised. Maybe we (the user and myself) are screwing
up the process by making it check the mail server before
it's ready? Not likely, but seems possible from
observations.

I have ~ 130 users configged same as original with the
PST on the LAN and this is the only machine giving me
problems.

Thanks for your suggestion.

Is she using the same DNS servers for external name resolution?
Can she telnet to the POP server's fully qualified domain name on port 110
and get a banner?

Yes, she's using the same DNS servers as the rest of the
office, I've even tried running with the Mail server's IP
in the POP3 address instead of the FQDN.

Yes, she can telnet to the FQDN and IP.
