Windows Server 2008 DNS, Active Directory stops working on HP Proliant DL 380 G5 and G4 servers

[Nosferatu]

Hi,

I have 8 domain controllers HP Proliant DL 380 G5 and G4 servers running MS Windows Server 2008 64Bit Standard/Enterprise Edition.
Each DC is running DNS server and the domain zone are Active Directory integrated.
No previous verson of windows domain controllers are present.
Everything was working fine until recently.
For the past few days, i have been getting the following errors and warnings on all of my DC's on a frequent basis (daily on some, longer on others)

Events: 1925, 1311, 1566,1865
Source: ActiveDirectory_DomainService

Events: 4000, 4015, 4004
Source: DNS-Server-Service

Events: 13508, 13526, 13562
Source: NtFrs

At that point the AD stops working. During this problem, network shares are accesible (also sysvol folder), dns name resolution working correctly but no ad replica are possible, no directory access are possible.
The problems go away temporarily when i restart the servers. But the next day or the day after that, it reappear. There's no specific timing, it's just random.

Let me clarify that nothing was changed. Everything was working fine for more than 4 months. Now all of a sudden, i am starting to have these issues.

I have gone through a lot of articles including the ones below, did all the tests mentioned in those articles. Still couldn't find the source of the problem:

Any help would greatly be appreciated. Thanks in advance.

Hello,

Yes the problem's gone on its own (apparently). The issue was appearing on almost a daily basis. What i did to avoid the issue was that I kept restarting all the DC's once every day for 4-5 days. Everyday I made sure to restart the DC's before the issue appeared that day. In this way I managed to avoid it. After 4-5 days, the issues did not appear, atleast not until now. It has been several weeks.
BTW If that does not solve it for you, it seems there's a hotfix available for this issue:

The hotfix is available for Vista only but if you check this article, it's mentioned that you can use that on your Windows 2008 computer:

"Note: If you do not see the option for Windows 2008 you can use the Windows Vista version on your SBS 2008 server."
