I am running windows 2k8 R2 RDS with 5 session host servers.
I am only using RDP to connect, there is no web based portion.
when any client attempts to log in i am asked for credentials twice if the session is redirected to a different session host from where the DNS round robin places the initial connection.
clients that i have seen this behavior with include
- XP SP3 with RDP v7 without NLA support
- win7 with NLA supported and RDP 8 support
- win7 embedded with NLA support and supporting RDP 7.1
I do not have the "always require password" checked
I do have "use clent provided credentials" checked
