Event 26001 is logged regularly on Windows Server 2012 R2 host computers
This article provides a workaround for the issue that event 26001 is logged every 30 minutes on Windows Server 2012 R2 host computers.
Original product version: System Center 2012 R2 Operations Manager, System Center 2012 R2 Virtual Machine Manager, Windows Server 2012 R2 Datacenter, Windows Server 2012 R2 Essentials, Windows Server 2012 R2 Foundation, Windows Server 2012 R2 Preview, Windows Server 2012 R2 Standard

Every 30 minutes, an entry that resembles the following is logged in the Application log on a computer that's running Windows Server 2012 R2:
Event ID: 26001
Task Category: None
Got null results from Select Connection from Msvm_SyntheticEthernetPortSettingData where InstanceId='Microsoft:4DB9D08C-D75B-483A-BC3E-5AA19B5FC50B\\335614F9-B1BA-45EE-A2DD-2168B7F86CDC'
This problem occurs because of a known issue that affects the System Center 2012 R2 Virtual Machine Manager Management Pack. This issue involves the rules that collect the virtual port sent and received data that appears in the virtual network dashboard. These rules use WMI v1 classes. However, these classes are not available in Windows Server 2012 R2. Therefore, the rules fail on Windows Server 2012 R2 host computers.
To work around this issue, disable the rules that are responsible for the query. To do this, follow these steps:
Open the System Center Operations Manager console.
Select Authoring, select Management Pack Objects, and then select Rules.
Select Find, and then locate the following rules.
If the console is scoped, select Scope at the top of the screen to remove the scoping on the view and display all rules.
- Virtual port sent Bytes per second
- Virtual port received Bytes per second
Right-click each rule, select Overrides, select Disable the Rule, and then select For all objects of class: Virtual Port.
At the bottom of the dialog box, select a management pack in which to store the override.
We recommend that you don't save the override to the default management pack. Instead, you can save the override to Microsoft System Center Virtual Machine Manager Overrides, or create a new management pack.
