I have inherited a Windows 2000 Server configured as a domain server. There was a previous proxy server in place that is no longer in use. Internet Explorer automatically configures itself, no matter the user, with proxy settings that can NOT be changed.
I have looked at local and network policies via poledit.exe and gpedit.msc, plus everywhere else I can think of, to no avail.
Even logged on as the domain admin, I can not change the proxy settings. They are just greyed out.
