    Hi there, hope someone can help...

    I have a computer network of about 50 computers.(35=Win98 & 15=WinXP)
    They are updated, and runs NAV2004.

    Ther is a File Server(Win 2000 Server), a Linux Internet Proxy Server, and a Linux VPN Server. Alll use DSL connection for internet and VPN.

    There is 2 x 16port switches, and some smaller switches around the building.

    It looks like one or more of the computers on the network is making the Internet
    Proxy Server freez/restart.
    Looks like the LAN card that hangs. I cannot Ping it if the proxy freezes.
    Could it be a virus, or malware program?

    How can i detect the computer or computers that is causing this problem?

    Could it be a virus,

    I tried to pull all the connectors out of the switch, and putting them back one by one, untill the problem came back. It did not work, cause when i took that computer out, the problem still came back. Even then when i tested the computer i took out, it did not make the Proxy freez!
    I just cannot pinpoint the PC causing the problem.

    This is just so frustrating!! :confused:
    I dont know what to do anymore.

    Please help !!!

    I'm going to move you to networking and see if the folks that hang out there have any ideas.

    May be the long way of doing it but have you thought about taking groups of PC's off the network and then seeing if it hangs? or as soon as it hangs take an inventory of the PC's that are on in the office and then eliminate the ones not currently on?

    Are you sure its not just a problem with the Linux box itself hanging?
