Q: Can I install a 2008 Licensing Server as a member server in my W2K domain?

A: When you install a 2008 TS Licensing Server in a W2K domain, you get the following error message:
“This license server is not a member of the Terminal Server License Servers group in Active Directory
Domain Services. This license server will not be able to issue TS Per User CALs to the users in the
domain, and you will not be able to track or report the usage of TS Per User Cals on this license server.”
When you try to add the TS LS to the group:
“The computer account for license server <Computer Name> cannot be added to the Terminal Server
license servers group in the Active Directory Domain Services (AD DS) because the license server is
unable to contact AD DS.”
“The following error occured on the license server: 0×534.
No mapping between account names and security IDs was done”
To solve the problem, and create the Terminal Server License Servers group in your W2K AD, you have to update the AD schema to a 2003 schema. That’s done by running the adprep utility.
