NISPOM requirement: Windows Session Controls

NISPOM requires (8-609-b1) that “if the IS supports multiple logon sessions for each user ID or account, the IS shall provide a protected capability to control the number of logon sessions for each user ID, account, or specific port of entry. The IS default shall be a single logon session.”

But Windows Server (all versions, from NT4 to the coming W2K8) does not allow simultaneous logon (same ID, same password) limitation or prohibition.

How do you deal with that? Thanks in advance for your contribution!
