Re: ANOTHER possible Windows problem?

David,

At around 3pm EST all of the Windows 98 boxes at my company suddenly 
turned their proxy settings on (we don't use a proxy) and set their 
proxy server to: cache.mycompany.com (substitute mycompany with the name 
of mycompany) and port 3128.

Now i know port 3128 is a Squid proxy port, so i guess that makes sense, 
but has anyone ever seen anything like this before? the few win2k boxes 
are fine, as are the linux boxes. Is there a trojan or something like 
that where the payload changes proxy settings?

or is it something else entirely?

it's the G8 conference I fear.

stupid wild guess, from one of the 'upgraded' machines, try pinging 
wpad.mycompany.com
and if that works out,  http://wpad.mycompany.com/wpad.dat or conf.pac or
whatever

If that works, find your DNS admin, and forgive him when he's using DDNS
;-)
