scom 2007

My entire OpsMgr environment runs SCOM 2012 R2 UR1.
Occationally I come across Windows Servers that dont have any Agents installed – or so it seems.

A couple of days ago, this happened. I came across three servers without an agent, and started the Discorvery wizard.
All servers was discovered successfully, and I stared to push agents to them.
After a minute, they all failed, and the AgentInstall.log file on the Management Server returned with this funny little fucker.

Turns out there was an old SCOM 2007 agent installed on all of them.
Apparently, while upgrading our environment from 2007 R5 til 2012 SP1, we missed these servers.
As the SCOM DB server and management group was created from scratch, we did not receive any events on servers trying to connect to the management group with an old OpsMgr Agent.

After manually uninstalling the 2007 agents, the 2012 agents was pushed successfully from the SCOM console.

Lesson learned.
