On a windows XP machine we have a problem that seems to be that it will not accept any incomming network connections even when there are xp firewall exceptions or the xp firewall is disabled.
When the machine is booted into safe mode connections work ok. When the machine is booted into normal mode but using msconfig to disable everything non-microsoft the problem is still there.
We do have mcafee virus scan enterprise but this was removed without resolving the problem.
We have tried microsofts network stack fix tool which did not resolve the problem.
Wireshark reveals nothing.
The only other network relevant software that we can think of that is installed is ciscoVPN client 5 but this is on all of our machines which dont have the problem.
We really want to understand this problem rather than just reinstall as it has happend on 2 of our laptops now.
Any help much appreciated.
