Half a year ago I created a policy to avoid users browsing internet on the terminal server. Now we need to allow again.

Tried to disable the policy "UserSettings/System/Internet Communication management/Restrict internet access" but nothin helps. Have rebooted the teminal server.

What to check for?

It's a policy that affects users logging on to ther terminal server.  

The policy is linked to the Terminal Servers OU that I created.

DNS seems ok since I can do NSlookups

RDP sessions from the terminal server against an outside server works.

FTP against outside ftp sites works

It's only Internet Explorer that dosent show anything at all. It says " Internet Explorer cannot display the webpage

"

Have you tried installing and uninstalling IE? Also did your group policy update?

If I disable the RestrictCommunication in the policy the GPRESULT /V shows me this:

GPO: JN Terminal Server Bruger indstillinger
                KeyName:     Software\Policies\Microsoft\InternetManagement\RestrictCommunication
                Value:       0, 0, 0, 0
                State:       Enabled


If I enable the RestrictCommunication in the policy the GPRESULT /V shows me this:

GPO: JN Terminal Server Bruger indstillinger
                KeyName:     Software\Policies\Microsoft\InternetManagement\RestrictCommunication
                Value:       1, 0, 0, 0
                State:       Enabled

So the state is Enabled no matter what I do.???????

Sounds strange. What does GPUPDATE shows in the event viewer if you disable the policy?

Tried this linkand rebooted. But no luck http://escapelogic.com/main/node/2.

As mentioned earlier I can do this:
FTP to external or internal sites
HTTPS to external or internal sites

but CANNOT do any HTTP trafic? Strange I think.

Don´t even know if this is a Policy bugging me. Have looked in the firewall log and it tells me nothing, so I don't think the firewall is blocking.

What else can prevent this damn machine from doing http????

Sorry for my above post. It was just a mistake(About file splitter). Have you run gpresult on the server? Does it show any errors?
