So tell us about your hosts file:
2. Date of last update
3. What MSN related entries are there
4. Attributes (read-only?)
In XP it's C:\WINDOWS\system32\drivers\etc\hosts (that's all, there might be a hosts.sam also, but that's just a demo sample).
If it's related to the security updates indeed, millions of people might be affected. As long as that didn't happen, it might be unrelated.
I havn't been able to sign into Messenger since yesterday after my computer updated.. After troubleshooting it says "Your hosts file contains MSN related entries which may interfere with name resolution. Would you like Windows Live Messenger to clean up your hosts file. Yes Or No." After clicking "Yes" it doesnt seem to work.
ANY help would be greatly appreciated, im going insane!
