Increase WMI Default Memory Allocation for ConfigMgr Server

WMI is an integral part of ConfigMgr (SCCM). Let’s see How to increase – WMI Default Memory Allocation for ConfigMgr Servers.

Many SCCM issues could be directly linked with WMI. One example is SCCM console connectivity issues, such as “The ConfigMgr Provider reported an error connecting to the ConfigMgr site database server.”

This could be because the server doesn’t have enough WMI memory to handle all the processes (old win2k3 servers).

Solution | FIX – Increase WMI Default Memory Allocation

The solution is to increase the WMI default memory. See the below steps to achieve the same.

NOTE! Please try this in a LAB environment. I don’t think it’s recommended to change the WMI memory configuration directly on the production servers. To be on the safer side, take a snapshot of the servers before the change.

1) Run “wbemtest” on cmd prompt
2) Connect to the “root” namespace (not “root\default”, just “root”)
3) Select Open Instance, and specify “__ProviderHostQuotaConfiguration=@”
4) Check “Local Only” for easier readability, and you will see the threshold values
5) Change the MemoryPerHost value to something greater – e.g. Double it (256 MB)
6) Save Property
7) Save Object
8) Exit

Script

Also, see the Sample VB Script Code:

Dim locator: Set locator = CreateObject("WbemScripting.SWbemLocator")
Dim wmi: Set wmi = locator.ConnectServer("", "root")
Dim quota: Set quota = wmi.Get("__providerhostquotaconfiguration=@")
quota.MemoryPerHost = 384*1024*1024
quota.put_()
Wscript.Echo(quota.MemoryPerHost)

It’s always better to restart the box after applying this change.
