SBS 2008 POP3 connector error 0x800ccc0d after a couple of days

Hi,

I've been testing SP3 for Exchange 2007 in SBS 2008 in my test environment.  After a couple of days, the POP3 connector wasn't retrieving the mail and was giving errors (see below).  It asks to verify the account settings (verified), and to check the internet connection is working properly (yes).  So if I restart the server, it comes back fine - then a couple of days later the same thing occurs all by iteself.

The error is:

[t 0] 11/10/10, 19:18:16: EVENT: An error occurred while accessing the mailbox for user [my email address] on the POP3 server [my mail server]. The error code was 0x800ccc0d. Verify that the server and account settings are correct, and that the internet connection is functioning properly.

A few different google searches have turned up nothing except "check your internet connection" (it's working fine).  Obviously, restarting the server every time this occurs is not feasible.

Has anyone else seen this problem before, or have any ideas how to fix it?

Cheers,

Tim.

Very strange. From the log it looks like you have intermittent DNS probs. On the other hand telnet is working..

How is the SBS connected to the Internet? 2nd NIC or the entire network via a router?
On the internal NIC, are the DNS server settings point to the servers internal IP? In DNS server, where are you forwarding to?
Maybe posting the output of "ipconfig /all" on the server would be good
in the meantime you may want to add the IP of your mail host to
C:\WINDOWS\system32\drivers\etc\hosts
If your problem goes away, its definitely a DNS problem.

When in error state: can you still resolve the pop3 servers name?
nslookup <pop3.mailservr>

Can you still telnet to your pop3 server?

telnet <pop3.mailservr> 110

Also enable detailed logging in POP3 Connector

Thanks, mate.

Have been able to telnet and nslookup when it's down.  In the meantime, it has magically fixed itself, then magically died again.

Verbose logging enabled, a little bit extra here:

[t 0] 11/12/10, 19:05:36: EVENT: An error occurred while accessing the mailbox for user '[me]' on the POP3 server '[server]'. The error code was 0x800ccc0d. Verify that the server and account settings are correct, and that the internet connection is functioning properly.

I believe it is a DNS problem.

Thanks for your help.
