SBS 2k3 – DFS & LicenseService problem

We have Small Business Server running on our domain as the PDC and this was fine, as we have grown we now have a secondary domain controller (2k3 std).

We ran out of licenses at one point and were receiving msgs on the server, we purchased another 15 licenses (total of 20 now) and the errors have stopped appearing on the server, however they are still being recorded in the event log.

when this happens some users on the network are disconnected from the DFS, they can access a direct mapping to a server, but nothing thats on the DFS until the reboot their machines…

there are no other related events anywhere in the logs… just the LicenseService 202 Event which occurs 4 times a day
