I have 2 domain controllers viz A and B. I have set group policy for X users. Now these X user do not have internet access, if they open internet they have access to our webamial. now these X users login with username Y from Z machines. Y user name has only access to limited things like selling application, and internet icon which works only for webmail. eveything was working fine for 3 yeras , but past few days i figured out that internet is being used from one of the Z machine.
Z (machine) OS: windows xp
Server : microsoft windows 2003
