At our office we have two master systems running with SBS 2008 server. One of these is used just for as a File Server while other is Domain Controller with the FSMO roles. We did this setup about a year ago and so far it was working great without any problems but until two days ago. Since past two days my File server is facing unexpected shutdowns. When we checked the Event Log, this is what we found:
Event ID 1074
The process C:\Windows\system32\silsvc.exe (FILE-SERVER01) has initiated the power off of computer FILE-SERVER01 on behalf of user NT AUTHORITY\SYSTEM for the following reason: No title for this reason could be found
Reason Code: 0x2000c
Shutdown Type: power off
Comment: Licensing Compliance Service caused a shutdown. Please look at the events under Microsoft > Windows > Server Infrastructure Licensing > Operational for details.
Event ID 38
The Additional Server Count Check detected a condition in your environment that is out of compliance with the licensing policy. This server will be automatically shut down if the issue is not corrected in 179 day(s) 11 hour(s) 0 minute(s). Please look for additional events for Additional Server Count Check to troubleshoot
The Additional Server Count Check in the Licensing component did not pass because error 0x8007203a occurred in function f4 [KOAU]. The server is not operational.
Make sure that your DNS server can be contacted and the following services are running: Active Directory Domain Services (NTDS), DNS Server (DNS), Kerberos Key Distribution Center (KDC). This server will be automatically shut down if the issue is not corrected.
Any idea what is meant by this? Please help.
