I am getting about a dozen such errors as are listed below on my Exchange Server 2003 / Windows Server 2003. I have tried disabling "Objects" in the "Authoring" space but to no avail. Not sure if this is common but with as many errors as I am getting here than I might be disabling the wrong objects. Look forward to a response.

Hi Bob,From this description:In PerfDataSource, could not resolve counter NNTP Server, Current Connections, _Total. Module will be unloaded. It indicated that this is a known issue which I mentioned in our last thread, we need to disable the rule.1. Navigate to the Authoring Space in the Console.2. Select Rules under Management Pack Objects.3. Type Performance Data Source Module in the Look for: box and click Find Now. Be sure a Scope is not set or filtering the Health Service Target.4. Find the rule, Performance Data Source Module could not find a performance counter under Type: Health Service (2), right-click, select Overrides, Disable the Rule, For all objects of type: Health Service.5. When prompted, Are you sure you want to disable this rule for Health Service? click Yes.Microsoft is working on the long-term solution to address this problem.--------------------Regards,Eric Zhang

Eric, I have done this several days ago and followed up / verified again yesterday. The rule is diabled as described above. The errors are still there and coming. Therefore there must ba another solution? Thanks, Bob

Hi Bob,It seemed that we need to disable the specific monitor, please try the following steps:1. Open SCE cosnole, navigate to Authoring spaces.2. Choose "Management Pack Objects" - "Monitors"3. Select "IIS 2003 NNTP server" - "Entity Health" - "Performance".4. Right click "NNTP Server\Bytes Total/sec baseline monitor", choose "Overrides" - "disable all objects of type: IIS 2003 NNTP Server".--------------------Regards,Eric Zhang

No, this is not fixed, I have just become tired of working on it for awhile. I will get back to it when I have more time. I have tried all suggestions to this date and they did not fix or change anything.

So ... is there a fix for this issue. I have found numerous threads with no fixes, just this "temporary work around". Thanks, Fergus

Aparently not. This is just one more of the many ignored issues they have decided does not really matter. I have not so much as received a hint that they plan on fixing it. Good luck and let me know if you here of anything more.

Hi Bob,There is a hotfix for this. KB951979.You can read more athttp://www.systemcenterforum.org/workaround-to-operations-manager-2007-sp1-performance-module-error/

Hi Eric, I imported all 4 management packs from KB951979 and still got the NNTP/SMTP performance errors. I'm running SCE 2007 SP1 on Windows 2003 Standard SP2 x64. There is Exchange 2007 on this server as well and neither NNTP nor SMTP services from IIS are installed on it. I mean the services are not DISABLED (as suggested in KB951979) - they don't exist at all. Thought we could sell it to customers as a Microsoft partner, but it would be a suicide considering post-sale support overhead. It's a very immature product. I spent many days to rectify all the problems I encountered, but it seems to be an endless battle.
