How do I transfer a Windows 2000 Terminal Services CAL to another computer?

Run the Terminal Services Licensing program on your Windows 2000 server (Start - Programs - Administrative Tools - Terminal Services Licensing)

Press Properties on the View menu.

On the Connection Method tab, press Telephone and your country.

Press OK.

Use the Action menu to press Install Licenses. This starts the Licensing Wizard and returns a phone number.

Call the CSC and describe your need to reissue licenses. The CSR will direct you how to continue.

Start the registry editor (regedit.exe)

Move to HKEY_LOCAL_MACHINESoftwareMicrosoftMSLicensingStoreLICENSE00x

Delete the LICENSE000 or LICENSE00x key.
(There may be two keys, one for the Windows 2000 or Windows NT computer and one for the TS CAL)

Close the registry editor
