How to manually expire Terminal Server licenses

I have 10 per device terminal Server CAL's installed and I cannot get the the server to release them even though 2 of the machines are not even in use any longer.

Unfortunately you can't! I know it sounds stupid but the licences expire automatically between 55-80 days of no activity.
The only option you would have would be to change the licensing mode to user cals instead as these aren't actively managed - but of course you'd need some new cals.
Sorry it's not good news!

Just wait. TS licenses that aren't renewed anymore by the client will expire after 52 to 89(!) days. During that time, a new client replacing an old one can work with a temporary license, as these are valid for 90(!) days.

I don't think this is possible.

"...License Recovery Process

Once a device has been issued a CAL, that device owns that CAL until it expires. Even if that device will never reconnect to the Terminal Server before the CAL expires, there is no way to manually recover the CAL. ...'

jvuz,
it's as I said, you only have to wait.
The emphasis in your quote is on the word "manually", not "recover". Check the following sentence: "License recovery is handled inherently by the expiration of CALs. Device CALs are valid for a maximum of 89 days; however temporary CALs are valid for 90 days. The license server runs a process every 24 hours to recover CALs that have expired and place them back into the pool."

This feature was first introduced with W2k SP3; check here for details:

oBdA, You're right. When I was writing my post, yours wasn't there yet.
