I must be forgetting a step in setting up NT authorization setup

I setup a local admin user and added to Crystal NT Users group
Added Group to Windows NT authorization
User is placed on users screen and I added to administrator's group

When user logs in they get the message below

Account Information Not Recognized
NT Authentication failed to log you on. Please contact your system administrator to make sure you are a member of a valid mapped group and try again.

I followed the BOBj support of adding the group to the local policy but still no avail.

OS: XP Professional
CE: 9 and 10

Thanks for your help
