Today i had a problem with my Microsoft System Center Operations Manager 2007 (SCOM 2007) environment. I am working on a transition from SCOM 2007 on Microsoft Windows Server 2003 to SCOM 2012 on Microsoft Windows Server 2008.
A part of this transition is that you need to move agents from 1(Root) Management Server (MS) to another. This can be easily done for automatic installed clients. You can go to your SCOM console and choose to “Change Primary Management Server” for that agen.
However, if you manually installed the SCOM 2007 agent for whatever reason, DMZ – firewall settings – etc, you cannot choose to change the Primary Management Server.
I have several manual installations and i really want them to report to a new Management Server in SCOM 2007.
I tried deleting the agent from the database and remove it from the agent server. Then reinstall it on that server. No luck.
I tried using “Change” for the agent in the programs and features part. A wizard shows up and you can choose to modify a management group. When asked which management server to use, you type in the new management server. Click install.
While installing i got an ESENT Keys are required error. I fixed this by opening a command prompt as an administrator and executing the following:
msiexec /I{25097770-2B1F-49F6-AB9D-1C708B96262A}
Now the SCOM 2007 agent installs and no problems are detected.
After a while i checked the console. I saw that the agent again was reporting to the old server. Not good!
The next thing i tried was deleting the agent from the database from the SCOM 2007 console. Then deinstall the agent on a server. On that same server i opened an administrator command prompt and stopped the System Center Management service.
net stop “System Center Management”
This was just to be sure the service was stopped.
In the same administrator console i needed to delete a non visible rule in the firewall.
netsh advfirewall firewall delete rule name=”MOM Agent Installer Service”
As you can see: one rule was deleted.
Now i tried installing the SCOM 2007 agent on the server by using a push install from the new Management Server. And you know what?
I hope this was informative for you.
