Hi
I have a network with 48 PCs among which 43 PCs are clients of a windows 2003 domain controller and others are not a part of domain. DSL router is connected to the main switch through which everyone is accessing internet. Now my problem is, when i try to connect one particular computer(Dell Optiplex 760 with Windows XP Pro) to an edge switch(which is connected to the main switch), everyone’s internet gets disconnected. As soon as I remove it from network, internet is working as before. I formated the particular computer completely and re-installed.Well,it worked for few days and now the problem started again. Weird part is sometimes the same computer works in the same network without making any problem. Anyone has any clue about such a problem? I couldn’t find any suspicious programs running also. Please help…Thank you in advance.
