SCOM 2007 - DNS MP external resolution monitor problem

Hello,

As several people who imported the latest DNS Management Packs you received many alerts regarding a problem with external resolution.

I found several blogs relating solutions was to override the host parameter of the monitor from www.microsoft.com to microsoft.com or to override the querytype parameter.

I think I found another part of the problem for people using non-US OS.

When I test the nslookup command on a french DC it returns successfully. So I checked the script used by SCOM NslookupAllTests.js and I figured out it was checking if the result of the command was matching some regular expressions:

but the string return in my case is in french:

So as the script doesn't find Non-Authoritative it returns a critical state for the monitor. My workaround for non-US environments (sorry): Disable the monitor.

SCOM 2007 - Exchange 2007 MP - Enable POP connectivity logon latency performance collection

Hi,

This is a post I had in mind like 2 months ago and totally forgot to share with you so here it is. I just hope it's not too late.

Today I'll deal with the Exchange 2007 MP (still the converted one) and some performance collection. After implementing the MP and tuning it I had still some views remaining deseperatly empty like the "Test-PopConnectivity Logon Latency" view:

What was weird is that I had events collected about Test-PopConnectivity so I looked at the rule that generate those events:

To check which parameters I could modify I created an override on all the CAS servers:

 And I discovered a lovely parameter called returnPerfDataForR...eports I guess but don't remember which was set to False so I turned it to True and saved my overrides in a specific MP dedicated to EX2K7 (Best practices !)

I waited for my override to be propagated to the CAS servers and guess what ? my view still remained empty. I decided to look at that PS cmdlet Test-PopConnectivity. I ran it the same way SCOM does but using a pipe fl to see all parameters:

And here was the result of the command with an interesting parameter called PerformanceCounterName which value was POPConnectivity-Latency:

After this intreseting discovery I decided to check the properties of my performance view:

And what the f*** ?? it was set to filter on a counter name called "Logon Latency" which I think is used for another performance view in the MP (copy/paste is evil !):

I then created a new performance view as a test:

And set it the same way the original view is but modified the counter name filter with the one I found in the PS cmdlet result:

 

And I could see that performance data were collected and that since I created the override:

 

I hope you find this post useful. I would be pleased to have some comments on this one as I'm not 100% sure this counter name issue is due to some Exchange configuration I don't have knowledge about.
