RemoteApp connection error: Server 2008 R2 with Windows 7 and RD Gateway

-

hello,

i’ve got situation i’ve configured w2k8r2 server remoteapp on internet (with rd gateway) , seems work great windows xp , vista, windows 7 clients cannot connect. 

after authenticating on rdweb page , clicking remoteapp ‘connect’, win7 clients message: 

“your computer cannot connect remote computer because error occurred on remote computer want connect to.  contact network administrator assistance.”  note:  no useful event messages produced on either client or server event logs when happens

the difference between windows 7 remoteapp working or not change rd gateway config ‘autodetect..’ make win7 work (instead of specifying internet dns name , ntlm authentication – xp work).  and, when remoteapp work win7 (when ‘autodetect..’ chosen) not show in rd gateway monitor!  in other words, it’s using rdp port firewall port 3389 instead, when don’t want to!  i’d shutdown port 3389 cannot because of issue.

question #1 : 

i understand win 7 uses nla authentication, therefore mean that, once specify ntlm, i’m stuck winxp being able use remoteapp on port 443? 

question #2 : 

why xp remoteapp users work fine going through rd gateway (port 443), when remove port 3389 access firewall these gateway users can no longer connect?  i thought rd gateway final (443 only), , did not depend in way on 3389 being open!? 

question #3 :   

windows vista seems work in both scenarios think win 7 remoteapp connection problems may have nla versus ntlm authentication.  although have continue support xp, clients moving win7 in near future.  is there @ least can windows 7 work in ‘vista authentication mode’, , if how?    and, choice xp, vista , win 7 working in harmony remoteapp across port 443? 

i've read lots of documentation , searched solutions have had no luck, on of appreciated. 

 

many thanks,

jon
