To quickly fix this, on that machine that cannot connect delete the registry key HKLM\Software\Microsoft\MSLicensing. This will do it.

Also make sure you check both TSs to see if they are both pointing (and being able to access) the licensing server you posted the screenshots from.

Thanks for the quick responces all.

Claudio - i can ping the licence server by hostname and fqdn from both the Terminal servers.

Michael - I checked that and both servers are set at per device CAL.

Is there anything else i can check for, im hoping it is just an issue on this particular XP pc that is trying to connect as i have not had any other calls yet.

If just one PC is experiencing this problem, delete the key as Claudio said, although I would delete it a couple of levels down from the one he specified.(this is on the client PC):

HKLM\Software\Microsoft\MSLicensing]Store\LICENSExxx   (where xxx = 000, 001, etc.)

Delete all the LICENSE subkeys you see in the MSLicensing\STORE key.  The license key will be regenerated automatically the next time the user logs on to a TS.

Well honestly there is no harm on deleting the whole key as I posted. It will get rid of all your TS CALs but you will get new temporary ones and once the 90 days are done they will become permanent again (assuming enough TS CALs available).
Given all you did so far, I would say you got a fluke with this one PC. Nothing to worry about.
Just keep an eye on all this for the next 90 days.
