MSN Messenger doesn't fetch contact list after SP2 upgrade

Archived from groups: microsoft.public.windowsxp.messenger (More info?)

Ever since I loaded XP SP2 on my PC, my MSN Messenger
(6.2.0137) no longer works.

Interesting it does appear to login to the server as it
will kick me off it if I had logged in from another PC.

It's just that the Contact List never comes back. No Error
messages, just the two dancers dancing around each other
forever.

I have Norton Internet Security Installed, tried de-
installing - no difference.

I have the new Micrsoft Firewall Disabled - no difference.

I de-installed SP2 - hi presto that works!

I put SP2 back on - and to my dissapointment MSN Messenger
again doesn't login fully again.

I'm sitting behind a NAT firewall, but that's not the
issue, as it obviously works whilst no SP2 installed. Also
have a second PC XP +SP2 behind the same firewall, where
MSN works fine.

Any help appreciated
