Question : Problem: One RDP Client can no longer connect to TS 2003 server.  Everyone else can...

One cleint out of the 25 using the same TS server can no longer connect to the TS server.  It is a 2003 server which has been running for about 2 years.  This is the error he gets:
 "The remote computer disconnected the session because of an error in the licensing protocol.  Please try connecting to the remote computer again or contact your server administrator."

This seems to have happened since we had a boot sector error on two drives and had to reactivate them through disk manager.

Also there have been lots os other permission related issues, such as one volume loosing all NTFS rights and registery settings.

The lisening server is online and the CALS have not been exceeded.

Troubleshooting steps taken:
Solution:  Perform the following steps:

Verify that the license server is correctly installed.

Verify that the Terminal Server Licensing service is running on the license server.

Verify that the client, the terminal server, and the license server can communicate by ensuring that Domain Name System (DNS) is configured correctly on each computer. To do this, run the ping command from each computer to each computer using the IP address, FQDN, and the NetBIOS name. If any of the ping commands fail, verify the DNS configuration on the network.

On the terminal server, set a preferred licensing server to connect to. You can do this by using the registry, a Windows Management Instrumentation (WMI) script, or, in Windows Server 2003 with Service Pack 1, you can use Group Policy settings or Terminal Server Configuration.

Solution:  If the previous solution does not resolve this problem, create a backup of the MSLicensing registry key and its subkeys on the client, and then remove the original key and subkeys by doing the following:

On the client, navigate to the following registry subkey: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSLicensing.

Click MSLicensing.

On the Registry menu, click Export Registry File.

In the File name box, type mslicensingbackup, and then click Save.

If you need to restore this registry key in the future, double-click mslicensingbackup.reg.

On the Edit menu, click Delete, and then click Yes to confirm the deletion of the MSLicensing registry subkey.

Close Registry Editor, and then restart the computer.

When the client is restarted, the missing registry key is rebuilt.

Answer : Problem: One RDP Client can no longer connect to TS 2003 server.  Everyone else can...

For whatever reason when the boot sector was reinstalled the TS liceing swithed back to Per Seat.  Microsoft had me switch back to Per User and now everything is fine.
