Slow system response when network cable is connected
Posted on 2009-05-12
I have an odd problem with a Windows XP Pro workstation: the system is slow and displays strange errors when connected to a network (any network). Some info about the system and problems:
- with the network cable connected, some commands take forever to run - 30s to get a response from ipconfig, 25s after trying to ping a host before the program output starts (meaning that I type the command, hit enter, and wait 25-30s before the system actually starts pinging the remote host).
- also with network cable connected, starting IE, the Control Panel, Add/Remove programs, takes around 30s - from the time that I double click the icon to the time that the program pops up and is usable.
Once the network cable is disconnected, the system runs and responds normally.
What I've tried so far:
- I've reset TCP/IP and winsock to default using netsh commands
- tried a different nic and disabled the onboard nic
- swapped cabling, used a different switch
- reinstalled SP3 and updated system and drivers.
- attempted to remove Windows Search, then simply disabled it and turned off any indexing.
- checked for viruses and spyware with 3 different products - nothing problematic found
- tried removing any programs that could interfere with the network - removed AV/Firewall software
