Active Directory Domain Services was unable to establish a connection with the global

[sidnuts]

We had a Blue Screen of Death on our server 2 days ago, so we decided to do boot from windows server 2008 r2 dvd and do a system restore from the previous night’s backup. Restore took around 6 hours, restore seemed ok until we checked the events and we got this error:

 

 

‘Active Directory Domain Services was unable to establish a connection with the global catalog.

 

Additional Data

Error value:

1355 The specified domain either does not exist or could not be contacted.

Internal ID:

3200e25

 

User Action:

Make sure a global catalog is available in the forest, and is reachable from this domain controller. You may use the nltest utility to diagnose this problem.’

 

Event id: 1126

 

Tried to resolve over the course of several hours, but just couldn’t resolve. So ran a restore over night to a previous months backup, in the hope that we could get the domain back up and running, then we could restore the previous days data backup. But unfortunately after the restore we got the same error.

 

Any help on this would be greatly, greatly appreciated.

Thanks in advance

Might be worth taking a dig through this if you got some spare time

did you not try and find what was causing the BSOD?

[sidnuts]

We did try and find out BSOD 'driver_irql_not_less_or_equal'...couldn't resolve this so then ran a restore.

 

Thanks steve21, have gone through that link previously...Ultimately the domain controller cannot establish a connection to the global catalogue server.

Sorted this problem, only took 7 hours.

Sorted this problem, only took 7 hours.

 

How did you sort it?

[sidnuts]

2 months ago, we brought a new server online to replicate our master... unfortunately the replication could not have gone correctly. It was only until we had the BSOD and restore from backup we realised the corruption.

 

We mainly followed the guides:

 

How to rebuild the SYSVOL tree and its content in a domain

 

The NETLOGON share is not present after you install Active Directory Domain Services on a new full or read-only Windows Server 2008-based domain controller

 

Plus a lot of arsing about. so every thing things seem to be ok.
