SRV2022 Domain Controller Issues

We are getting increasing amounts of SRV 2022 (Description: the server was unable to find a free connection) on a couple of our domain controllers. Can someone please advise?

i'm only wondering if there is a shortage of GC's there and these few are getting hit hard

i'm assuming these are gb interfaces?  the kb article mentioned possible network and hard drives as being affected.  are these physical or virtual servers?  have you tried rebooting?

take a look at this article

http://support.microsoft.com/kb/317249

you didn't specify what version of windows, how many servers, etc.
could you elaborate more on the systems involved and their roles?
might help to understand the problem better

Hi Seth2740. Sorry about that. Windows 2003, 145 domain controllers in that site.

11 DCs are reporting these kind of errors. None of them holds a FSMO role.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

I'm looking into the article.

Yep, 145 DCs at that site. It is a huge environment. Users are approximately 200,000.

I have to check and let you know. Which hardware in particular you think is causing this?

syseng007Author Commented:
I checked and CPU usage is low, however disk I/O is over 500 read/writes.

anything...disk, memory, nic
i'm leaning less to that though and more to an os/environment issue but just wanted to be sure
maybe these particular domain controllers are getting hit hard with something causing a bottleneck

do these provide any other services besides dc/gc?
how many of these 145 are also gc?

syseng007Author Commented:
No there are just DCs/GCs.

I have to get back to you to see how many are GCs.
