hi everybody,
recently I've installed a new server 2008 r2s with rdg and made a test configuration. Our users should connect from outside our company over that rdg server to our rds server (also 2008r2). I followed some technet guides and the configuration seems ok for me, but whenever I establish the initial connection to the rdg it takes overall about 1-1.5 minutes from clicking connect until my rds desktop appears.
After I press connect the credentials box appears instantly but then the connection process stands still during "configuring remote session..." (about 60 - 80 sec.) and then it switches once to "securing remote connection" (approx. 1 sek) then back again to "configuring remote session..." and then the desktop appears.
My system:
- RDS & RDG are Windows Server 2008 R2
- We use an external wildcard certificate and internally an domain certificate issued by our ca
- Incoming connections pass our TMG 2010 where a listener to our public name is configured
- we created some rules for the external communication (80, 443 inc -> RDG) and some internal (RDG -> RDS 3389,80,443; RDG -> DC DNS,kerberos; RDS -> DC dns,kerberos)
What I have tried already:
- all test clients (windows 7) unchecked "bypass RD gateway server for local adresses"
- I actively denied incoming connections on 3389 on our TMG (read in a forum)
- I traced the connections and found two connections that made no sense for me: some ms before the client connection succeeds our rdg tries to contact two austrian ips that belong to our isp (i'm not too excited about that....)
I'm looking for a solution for quite a while now but I didn't find any other possible solutions... I suppose i am not the only one with such a problem :)
best wishes
