Hello Vera,

Thanks for your reply

We haven`t decide yet about the logon procedure, one option is to allow the machine to log on automaticaly in Windows, in a very secure locked-down enviroment which will give the user only the possibility to start a TS session and then the user will have to use the credentials to login and get the applications, after the work time the user will log off from TS and another user will be able to log in. During the evening a script will shut down the workstations to save energy (or the last user will shut the workstation down)
Another option is to allow users to log on in Windows and have a roaming profile and then log on in TS and have a TS roaming profile but i don`t see why the users should log on 2 times if they are going to work just with the applications on the TS server.
We are planning to use 2003 TS server and we have a mix of 2000/XP clients.
I hope i gave you a good description about our purpose.

Thanks again!

As I wrote, Single Sign-On is not a native feature of Windows 2003 TS. You will need to buy a 3rd party application to get this (there are many with this feature, but most don't come cheap if this is the only reason you need them).

The only cheap work-around that I can think of is when you start the TS session automatically through a login script on the client, which you put in the Startup folder or the registry.
You could let that same script log the user off the client. Something like:

start / wait mstsc.exe
logoff.exe
