well this will depend on the SP rev of Windows 2000.
Lets assume for this you are running SP4 (if not you may need a HF depending
on SP rev)
Assuming this the License that you have issued to the PC will just sit in
that database unused (meaning that PC/windows build) . Now the temp license
you have been issued (to that same physical pc) is good for 90 days. That
issued license will just sit in the database and if the original PC never
reconnects (cant been rebuilt) the license will return to the available
pool, before the 90 day temp expires. This allows that PC to recoupe its
original license.
Confusing I know. All spelled out with this stuff, (link at the bottom)
Automatic License Token Re-issuance
Current Behavior
TS CAL tokens are issued for each device, and are stored locally on each
device that connects to a Windows 2000 Terminal Server. If a device loses
this TS CAL token through hard disk failure, clean reinstallation, or other
method, the TS CAL token remains assigned to that device. The only way to
recover this TS CAL token is to place a phone call to the Microsoft
Clearinghouse. The telephone number is (888) 571-2048.
Enhanced Behavior
An expiration period has been added to each TS CAL token that is issued.
This expiration period is a random number of days between 52-89 days of
issuance. When a client connects to a Terminal Server, this date is checked.
If the expiration is within 7 days, the Terminal Server connects to the
License Server and renews the TS CAL token, giving it another expiration
period of 52-89 days. If the License Server is not available, the TS CAL
token functions as normal, with the Terminal Server attempting to replace it
at each login. Upon expiration, the License Server returns any TS CAL token
that has not been renewed to the group of available license tokens.
For example, an unlicensed device connects and receives a TS CAL token with
an expiration period set at the maximum of 89 days. The device's operating
system is then reinstalled. The device then connects again. Because no other
TS CAL tokens are available, the device is issued a temporary TS CAL token
so it can connect for 90 days. On day 89, the original TS CAL token is
returned to the group of available licenses. The next time this device
connects, the Terminal Server presents the device with the full TS CAL token
that was returned to the group of available license tokens.
With the addition of these fixes, it should not be necessary to call the
Microsoft Clearinghouse to recover lost license tokens. If a device loses
its license token, the administrator can be confident that license tokens
that are issued after the enhancement was installed will be recovered
automatically.
IMPORTANT: There are a few cases in which license tokens will not be
recovered automatically:
a.. License tokens are issued prior to the installation of this hotfix.
Only TS CAL tokens that are issued after the installation of this fix will
utilize the re-issuance logic. A TS CAL token that is issued to a device
prior to the installation of this hotfix will remain assigned to that
device. The Clearinghouse must be contacted to recover any TS CAL tokens
that are issued prior to the installation of this hotfix. Because of this,
it is important that this hotfix be installed on all Terminal Servers and
Terminal Services Licensing Servers in an enterprise.
b.. Catastrophic failure that results in the loss of the licensing
database. In the event of a failure that results in the loss of the
licensing database when a known good backup is not available, Terminal
Services Licensing must be reinstalled and reactivated. The Clearinghouse
will then need to reissue any previously issued License Key Packs. The
License Key Packs that were originally issued are based on the License
Server ID at the time of issuance. If the License Server ID changes, License
Key Packs that are based on the old License Server ID cannot be installed.
