Without any warning I have been unable to access my email account. This also
happens to another user on the same PC.
The OS is XP Pro w/sp2. The error message is below.

The server responded with an error. Account: 'mail.comcast.net', Server:
'mail.comcast.net', Protocol: POP3, Server Response: '-ERR AVG POP3 Proxy
Server: Cannot connect to the mail server!', Port: 110, Secure(SSL): No,
Server Error: 0x800CCC90, Error Number: 0x800CCC90

So far, I have deleted and reinstalled the mail account. I have tried
changing the password. I have uninstalled TCP/IP and then reinstalled it. I
have conferred with Comcast. I got to a rep who after hearing what I had
done suggested a possible virus. AVG did not find anything. After all of
these attempts, I did a power down and restart to be sure that OE was
looking at the latest configuration.
I am running Kaspersky's on line scanner as I write. It will take a while
for it to finish, but as yet is clean.
There is the thought that IE/OE may have gotten corrupted. Unfortunately, I
do not have an XP Pro CD. This box came with the hated Product Recovery
Disc that cleans off everything. That is a NO-OP. However, I have a second
PC on my network that seems to be working. This came with a CD for XP Home.

Question: Is it OK to use the Home CD to repair/reinstall IE/OE as described
in KB 318378?

What have I missed?
