Remove old MP from MPList

[ajhawkes]

Hi All,

Can anyone tell me how to remove my decommissioned MP from my MPList when running:

http://mp/sms_mp/.sms_aut?mplist

It still returns my old MP that was decommissioned weeks ago.  I think this may have something to do with my clients not staying connected and active in the SCCM admin console.

<MPList>
  <MP Name="US-SCCM.mycompany.COM" FQDN="US-SCCM.mycompany.com">
    <Version>9106</Version>
    <Capabilities SchemaVersion="1.0">
    <Property Name="SSLState" Value="0"/>
    </Capabilities>
  </MP>
<MP Name="US-SCCM2.mycompany.COM" FQDN="us-sccm2.mycompany.com">
  <Version>9106</Version>
  <Capabilities SchemaVersion="1.0">
  <Property Name="SSLState" Value="0"/>
  </Capabilities>
</MP>
</MPList>

Many thanks in advance!

How exactly did you decommission the MP from ConfigMgr?

Hi Garth!
I needed to upgrade from a 2012 r2 server to a 2022 server. I created a secondary SCCM site server (2022) and had it in passive mode. When it appeared all was healthy, I promoted the new server to the primary and the old site server (2012 r2) was now the secondary in passive mode. Everything appeared to be healthy and working, so I then turned off the 2012 r2 server and removed the roles from SCCM.

@ajhawkes You should have left he server up and running while you removed all the roles from ConfigMgr. This way it would have cleanly removed everything.

@Garth-MVP thank you for that info, I will do that next time...I am planning on making another site server to keep in passive mode going forward.

Any suggestions on removing that old MP from the MP list on http://mp/sms_mp/.sms_aut?mplist, or where that data is stored or retrieved from?

IMO the simplest way is to turn the server back on and force the MP to reinstall them uninstall it clearly. The hard way means lots of search to find a supported method to clean up the issue or to contact MS support.
