one of our systems behaves in a strange way...
i changed the DNS IP address of it to 217.219.x.y .
but when i restart it it changes to 85.255.w.z .
and cann't browse any sites ...
why is it so ?
i have Symantec Antivirus installed on it which is updated every day.
and scan the computer with it but nothing has been found !
what should i do ?
