Windows RDS....Can't access externally?!

[R.O.S.S.I]

Hi all, recently looked at rolling out Windows RDS to our company and after setting it up and it looking as though its running fine internally (getting users to connect up to the server through thin clients etc), i'm having a problem getting the external Web Access functioning properly.

It's basically just set up at the moment with a Remote Desktop icon so users can just click this when they log into the web access page which should take them direct onto the server on their account.

The problem I'm having is that for some reason when people are clicking this it is basically saying 'Remote Desktop cannot find computer .....' as per the screenshot below.

Does anyone know why this is happening for external users? It works fine when I go to the site on our internal network, but its kinda useless on working internally!

Thanks.

ubern00b - We don't have a hardware firewall as such. We've got a Draytek 2820n. Would it be port 443 or would it be 3388/89 for RDP that I need to allow through?

tribz - not sure exactly what you mean by that, is that what i've described above? Also not sure what you mean about the RDP client on the users desktop. It shouldn't need configuring as the RDS Web Access should point him to the right machine shouldn't it?

Hmmmm I'll have to check the RD Gateway tomorrow then to see if there is any config I can change. And also see if there is anything I can set up on the router!

Couldn't see anything blindingly obvious in the RDS Gateway options etc.

Anyone any more ideas? I'm stumped!

Hmmm followed that guide through and people still can't get to it. The port forwarding looks as though its set up right too as I can get to the web access pages, its just when we click on the app it brings up that error!

As above, seems like DNS related to me.

Looks like the web-page is forwarding the local DNS name, and this means nothing to the external client.

I thought that RDS gateway took care of this... Do you need to use a certificate?

Not sure?

We've got an SSL cert for the site if thats what you mean?

How do I go about configuring it so the it forwards local DNS name?

Sorry for the n00bness, its all new territory for me this!

Hi guys, managed to sort this, was such a simple setting id over looked in the RemoteApp settings. I'd put the internal DNS name in rather than the external FQDN to connect to.

Chucked it in and bam, working!

Thanks for all your help and suggestions!
