Win 7 Pro error check update after Join Domain

[NothingKai]

Hi All,

In company system, all computer use Windows 7 Proffessional.

AD is Windows Server 2008, Fortigate Firewall.

After join domain for all computer, it cannot check update.

But when I unjoin domain, check update success.

Both instances I have used account local of computer full permission.

Hope everyone support.

THANKS !

Check the firewall on the domain - it sounds as if the application of Group Policies may be blocking the access to Windows Update.
Specifically, check whether WSUS is being applied - and if it is, that the WSUS server is where the policy thinks it is.
