We have configured TS Web Access which uses a Terminal Server Gateway to connect to a Terminal Server running end user applications. Both machines are running Windows Server 2008 Enterprise x64. We have mixed domain controllers (Some Windows Server 2003 and some Windows Server 2008). We have 2 problems.
First I am unable to set the default domain for either of the servers and when users attempt to login they are required to type the domain prior to their username (Domain\Username). Obviously this confuses them and often they are unable to connect. I have tried editing the registry by creating the 'DefaultDomainName' key and setting it to our domain, but that did not work. Also I tried editing the group policy setting <Computer Configuration><Administrative Templates><System><Logon><Default Domain> on the Windows Server 2008 domain controller. No luck their either. Is there something I am missing or does anyone have any other ideas that might help?
The second problem is that I would like the user to only have to sign in once, instead of being prompted at the TS Gateway and the Terminal server itself. I have read about Single Sign on (SSO) but that does not work with Windows XP machines. Thanks in advance.
