When I try to disable the LAN on a client's machine, I get a message titled "Error Disabling Connection" with the contents : "It is not possible to disable the connection at this time. This connection may be using one or more protocols that do not support plug and play, or it may have been initiated by another user or the system account."
The client's PC is WinXP Home.
I have disabled/enabled in the device manager - no joy
I have uninstalled and reinstalled at the next boot - no joy
I have started in safe mode with networking - no joy
I have googled extensively - no joy
The cryptographic service is running and has been restarted with no errors that I can tell - no joy
I have run anti-virus and anti-malware programs and a registry fixup tool - no joy
I have rebuilt the TCP stack with WinsockXPfix - no joy
I have made sure there is nothing funny in the used items area of the General tab of the connections properties.
I have run HijackThis and removed everything unknown - no joy
I'm out of ideas here. I should be able to disable this thing in the network connections, but cannot.
How can I figure out where the problem is?
