sbs 2008 180 days shutdown event 38 and 4

I'm trying to solve a problem in a friend server.

i'm working on a Small Business Server 2008, it's a DC, NO sharepoint, NO Exchange (there is another software), NO DHCP (firewall do it), WINS and DNS enabled.

Some days agoo Server has shutdown and in event viewer i found this 2 errors:

38 and 4

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 68 day(s) 19 hour(s) 30 minute(s). Please look for additional events for Additional Server Count Check to troubleshoot."

Event ID 4:

"The Additional Server Count Check in the Licensing component did not pass because error 0x8007200a occurred in function f1031 [PFVK]. The specified directory service attribute or value does not exist.

I tried slmgr.vbs -dli and it's Licensed correctly.

So i ran dcdiag /q and i've seen many errors like this:

EventID: 0x0000168F

Deleting dynamic of the DNS record '_kerberos._tcp.dc._msdcs.dominio.local. 600 IN SRV 0 100 88 server.dominio.local. 'failed on the following DNS server.

I ran dcdiag /fix but problem still remains.

I really don't know how to fix this issue... Anyone have an idea?

I also thought to use, in the extreme case, -ream , like slmgr.vbs -rearm, but i don't know how many times i can rearm server.

Thank you and have a nice day
