The symptoms of a corrupt TCPIP stack on a server are: after reboot it hangs at applying computer settings, users are unable to browse network shares, network browsing in general is slow, user can’t log in to the computer with message that the domain is unavailable or your computer account does not exist. Such can be the case with a corrupt TCPIP stack. When a symptom looks like something you’ve seen before but isn’t you can quickly find yourself going down a very dark tunnel.
The most difficult thing about troubleshooting a system is that such much of the skill is dependent on experience.
