The full text of the error message would be helpful. That includes the
server name, server type, port number, socket error code, SSL, etc. For
best results, copy/paste the error message rather than retyping it. You
should be able to highlight the message text in the error window (hold
down the left mouse button while dragging the mouse over the text).
Then press Ctrl-C (hold down the Ctrl key while pressing the C key) to
copy the highlighted text to the Windows clipboard. You can then paste
that text into the problem description using the Ctrl-V key combination.

If you have your anti-virus set to scan e-mail as it downloads, or an
anti-spam program, either of those could be causing the problem. This
could also be your firewall incorrectly blocking Outlook Express or the
mail ports (typically 110 for receiving and 25 for sending).

Getting an error in outlook express when connecting to POP servers of
my isp.

An Unknown TCP/IP error occurred 0x800CCC40

This error seems to relate to Winsock.

Have reset the tcp/ip stack using the netsh int ip reset command and
also
reset the winsock and winsock 2 registry entries using winsockxpfix

Anyone any other ideas?
