Terminal Server 2008 Client Cannot Connect

We purchased two new servers with  SBS 2008 Premium pre-installed and setup the second server to run Terminal Services. Initially this worked OK and we could connect to Terminal Server from PCs on the LAN, however after a few weeks (the project was temporarily delayed)  connections to the terminal server from any computer on the LAN failed. I thought that the problem was that the "grace period" to install a Licensing Server had expired so installed License Server on the SBS Server selecting "per user" mode, we have not yet purchased TS CALS but I understood that there was a grace period for the TS CALS of 60 or 90 days. I need to know if the problem is just a licensing problem that will be solved once we purchase the TS CALS or  if there is a different problem ?

After the grace period of TS ends, it must be able to contact a working TSLS.

"The grace period ends after whichever of the following occurs first:
- A permanent TS CAL is issued by a license server to a client connecting to the terminal server.
- The number of days in the grace period is exceeded."

"a few weeks" sounds however a little bit short to be licensing problem as the grace period is 120 days.
Do you find any related in eventlog?
What error is displayed when trying to connect?
Has firewall been enabled without configuring it to allow port 3389/TCP?
