RD Gateway Server Credentials.

Hi,

Having a difficult time setting up the gateway service.

We are running 2k8R2 with just(all) the rd services on it.  It is a member of our 2003 domain.

I was having certificate issues but I believe they're behind us.

From our internal network we can access the remoteapps and use remote desktop to connect to any of our machines by name or ip.

Externally however we cannot. 

using the apps.xxx.xxx we connect right to the box and see the published apps.  After clicking on any of the displayed apps we get prompted for the RD Gateway Server Credentials.  After entering anyone of many very valid userids, it reports that "The logon attempt failed." If I use an invalid username like blah it just reprompts for the username with no error.

I've checked every log in town and all I see is the I was sucessfully logged on and then immediately thereafter logged off, with no error.

Perhaps more telling is when I use the remote desktop connection, from the web access and to try and connect to any computer on the network by name, I get the following error- "Remote Desktop can't find the computer "xxxx". This might mean that "xxxx" does not belong to the specified network.  Verify the computer name and domain that you are trying connect to.  If I use the ip address instead, I get "Remote Desktop can't connect to the remote computer for one of these reasons: 1) Remote access to the server is not enabled 2)The remote computer is turned off 3)the remote computer is not available on the network - Make sure the remote computer is turned on and connected to the network, and that remote access is enabled.

I can from the RD server when logged on to it locally or remotely via rdp, rdp to any other machine in our network via name or IP.

I have nothing defined for the rap and the cap clearly should allow me access.  If it was a rap or cap issue, I would expect to see that in the logs, which I don't.

Any insight you may have will be immensly appreciated. 

Thank you,
Jim
