Extracting Windows 2000 Server CAL Product License code

Last Modified: 2010-04-13
We supplied an end user with Windows 2000 Advanced Server Retail - 50 User some time ago.

They're having to replace server - they have all the original documentation but cannot find the
CAL license key (s).

Microsoft say they can transfer or reissue the CALs onto the new server but need the original
licence key.

Is there any way to extract this from the original server ?? They have the Windows product
license key - just not the extra CALs

Thank You
