Terminal Server Authentication fails

Medium Priority

Hello,

Ive setup a new TS farm with session broker enabled. One dedicated brokerserver, and four terminal servers.

Until today, i could login fine. I had some trouble when people were trying to login. They entered credentials, and logged in. However, after 3sec, the user gets prompted to login again. Event viewer said that might be caused by license trouble or an invalid certificate. After going through everything, and using a 3rd party certificate, it finally worked.

But now i faced another problem. When i log in to the session hostname, or directly to one of the terminal servers, i enter credentials and login. But then the following error occurs:

The remote computer requires that authentication be enabled to connect.
Remote computer: xxxx.xxxx.xxx
The connection cannot proceed because authentication is not enabled.

On the TS Configuration, Security layer is set to Negotiate, and Encryption level to Client Compatible. NLA is disabled, as there is only WinXP computers as clients (using XP SP3/RDP 6.1). Remote settings on the TS servers is set to accept connections from any version of RDP.

Ive tried changing lots of settings, but i still cant get it to work.
Any ideas?

I had the same problem last week when I was learning/testing Session Broker in a VM test environment.  I also had XPsp3/RDP6.1.  I would love to know the answer.  One thing I did discover is that it worked fine from a Vista client.
