DNS 2008/R2 Resolution Time Alert & DNS 2008/R2 Server Responsiveness Alert
-
Hi all,
I've got a problem I'm trying to diagnose in SCOM 2007 R2 and the Windows 2008 R2 DNS Management pack v6.0.7000.0.
After installing the management pack as per instructions (enabling proxy agent discovery on all the domain controllers/dns servers), I keep getting 2 errors. These errors are coming from multiple domain controllers, but they seem to be regional domain controllers.
Critical Error 1: DNS 2008/R2 Resolution Time Alert
Warning Error 2: DNS 2008/R2 Server Responsiveness Alert
When going into Health Explorer, I can see the DNS 2008/R2 Server Responsiveness monitor is in a warning state, and the DNS 2008/R2 Resolution Time Alert monitor is in a critical state. Under the State Change Events tab, the "BestTime" and "WorstTime" for the resolution time monitor is 0 seconds. I can see that the default "Threshold Seconds" in the management pack is 1 second. When monitoring "Local Time Resolution" of the server, nothing takes longer than 0.6 seconds to resolve.
As a test, I created an override, and tried 5 seconds, 10 seconds, 30 seconds, 90 seconds and even 1000 seconds just to see if I could make it so the monitor doesn't trigger - but I've had no success yet. Everytime I reset the health, next time the script runs (which is every 15min), it triggers the montiors and throws an alert.
Has anybody come across this issue before? I've seen a few posts on the internet that this was a problem with the previous version of the management pack with Windows 2008/R2 - but from what I've read it is suppose to be fixed in the current version I'm using.
Any ideas? I'd rather not disable the monitor but it is an option if there is no fix for this.
Thanks in advance,
Noel.

Hi,
Please let us know the exact error message in the alerts. Meanwhile, please go to your DNS server and check if the issue exists.
Regarding this issue, please also try the methods in the following posts:
DNS MP – Noisy resolution time alerts, and how to deal with them
Error alerts from the DNS MP – script failures, WMI Probe failed?
If the issue persists, please also check the Event Log on both the management server and the DNS server; if there are any related errors, please let us know the details as well.
Thanks.

as far as i know they haven't really fixed the monitors themselves. just tried to have them run at different times.
i dont have experience with the new mp myself. We've adjusted the previous DNS mp ourselves and we're still thinking about going back to the new MS one.

I've recently upgraded as well and am seeing the same issues I saw with the older one. This particular monitor is raising alerts when the resolution time is 0. This doesn't make sense. I think this monitors script is faulty.
We actually reported this to Microsoft but had no success getting it resolved.
