Applies to Windows 2003 Server

Problem:
Your remote desktop clients are getting licensing errors such as "cannot upgrade license" or "license has expired" while trying to connect to a Windows 2003 Terminal Server.
This can happen to users trying to login from "Remote Desktop Connection", rdesktop, TSclient (Linux rdp Clients).

Solution
Server Side Solution
Microsoft has confirmed a bug where...
Terminal Services licensing mode changes from Per User or from Per Device to an invalid value after you add or remove a Windows component
http://support.microsoft.com/?kbid=834651

The key which controls this setting is:
Code:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TerminalServer\LicensingCore\PolicyAcOn

you mite not even have this key so...

To Add or Change this key...
Use Group Policy (best practice)

1. Open Group Policy.
Code:

start>run>gpedit.msc


2. In Computer Configuration, Administrative Templates, Windows Components, Terminal Services, double-click Terminal Server Licensing Mode.

3. Click Enabled.

4. Click either Per User or Per Device, and then click OK.

A Per Device CAL gives each client computer or device the right to access a terminal server that is running Windows Server 2003. A Per User CAL gives one user the right to access a terminal server from an unlimited number of devices.

1. Update Group Policy.
Code:

start>run>gpupdate

Temporary Work Around For XP clients
Rename this key from:
Code:

HKLM\Software\Microsoft\MSLicensing

To..
Code:

HKLM\Software\Microsoft\bkupMSLicensing
