I have removed a proxy server from our environment (Server 2008).
I have manually deleted the Microsoft ISA firewall client from the machines.
I have removed the PROXY server references from the controlling GPO.
About every 30 minutes the PROXY settings come back alive on the XP machines.
So I set the GPO to cause the PROXY settings to be by machine and not by user. No help.
I have edited the registry for the .DEFAULT USER . No help.
I'm pretty exhausted after a week of fighting this. Any help?
