Computer started locking up

I have just recently moved our server for our POS systems, only to find out that it now locks up at the login prompt or if you luck enough to log in shortly after that. I noticed that if I leave the network cable unplugged it works just fine and after I plug it back in it still works??? So, what is wrong and how can I fix it? It is a Windows XP system. Thanks!

    Looks like a DNS issue.

    Make sure the TCPIP properties have the correct DNS info if it is using a STATIC DNS entry..

    The server locks up, or the POS systems lockup?

    The server locks up. You cannot even get far enough into windows to run the POS program. It happens at the login prompt and shortly after the desktop loads if you get that far. speshalyst that is not the problem because it gets its IP through DHCP.

    Check what programs are loading at startup: start - run - msconfig - click the "startup" tab - disable all - re-enable internet security software.
    Click the "services" tab - check the Hide all Microsoft services button - disable all - re-enable internet security;
    Re-boot.  Any change?

    OK.... I Disabled everything but the microsoft services and did not re-enable internet security because I am not sure what you meant. I left the network cable in and rebooted and it came up just fine. So, I guess my next question is...
    Will I be fine leaving all of those services disabled??

    Glad to hear you are now up and running.
    By internet security, I mean a firewall (if you have one) and anti-virus software (which you should have) plus maybe any realtime spyware scanners that you have running.
    The task now is to go back into msconfig and start re-enabling programs and services and re-booting each time until you find the service or program which is causing the problem...

    Good luck!
