After performing a system state restore on a different hyper V hardware, Active directory seems to run on for a little bit then we lose it. When opening Active directory we get a message ad  I restarted the active directory service and it looks like it started workign again after about 10 minutes. The event log points towards the global catalogue missing, but im not sure why this would be after a system state restore ScreenHunter_21-Jul.-26-22.51.jpg

Seems like your DNS is not updated or have some staled records. you'll need to enable scavenging on it. make sure that all your domains are replicating properly.

use repadmin /showrepl and repadmin /replsum to see the replication.  you can add /e parameter to include all DCs in the forest.

make sure all firewalls are disabled.

I would also highly recommend that you install an additional new DC as soon as possible and demote this one that you got from a recovery. it's not recommended to work on recovered DC in production environment.

Early this morning I made the call to Microsoft and it was an issue with the file replication service
And the netlogon and sysvol were no longer shared causing the issue.

Yes we are planning to migrate the email off to office365
And then will make a decision on the rest

The reason for recovery was because of a crypto virus that got onto the c drive

The resolution for the issue, Server 2008R2 , system state restore, global catalog missing;
 
You had opened the case with us for issue, Domain Controller 'SERVER.domain.co.uk' is failing test advertising in dcdiag.
We found that, DC was in Journal Wrap
1.) DC was not advertising as GC.

2.) Checked DCDIAG, it was failing connectivity test.

3.) Checked using net share command and the sysvol and netlogon shares were not shared.

4.) In the events found that the DC was in Journal Wrap.

5.) Performed authoritative restore for sysvol as follows;
---------------------------------------------------------------------------------------------------------------------------------
i. Click Start, and then click Run.
ii. In the Open box, type cmd and then press ENTER.
iii. In the Command box, type net stop ntfrs.
iv. Click Start, and then click Run.
v. In the Open box, type regedit and then press ENTER.
vi. Locate the following key in the registry:
-- KEY_LOCAL_MACHINE\System\CurrentControlSet\Services\NtFrs\Parameters\Cumulative Replica Sets
vii. Below the Cumulative Replica Sets subkey, locate the GUID.
viii. In the right pane, double click BurFlags.
ix. In the Edit DWORD Value dialog box, type D4 to complete an authoritative restore, and then click OK.
x. Quit Registry Editor, and then switch to the Command box.
xi. In the Command box, type net start ntfrs.
