The case is a XP sp3 system running at a remote location.
It has 3 NIC?s and 3 different IP address.
Occasionally this machine becomes totally silent and deaf on all 3 networks.
A Fluke analyzer hooked on are not able to see any activity.
If the machine is rebooted, everything is normal for some days until it happens again.
I have received forced kernel dumps both when normal and when the problem occurs.
Dumps are opened in windbg and symbols are OK !
Problem now is that I haven?t any idea of where to look to reveal the cause!
Suggestions are welcome!
Is it possible to see what the XP firewall has blocked?
