Having successfully deployed some agents to some recalcitrant hosts, Iâ€™m now trying to address a false positive issue on a DC. Iâ€™m getting an error regarding â€œAD Op Master Respone [sic] Monitorâ€. The host has a recurring error:
AD Op Master Response : The script ‘AD Op Master Response’ failed to create object ‘McActiveDir.ActiveDirectory’. This is an unexpected error.
The error returned was: ‘ActiveX component can’t create object’ (0x1AD)
This led me to a blog post suggesting that the AD Helper Object needed to be installed. So I look in the OpsMgr hostâ€™s AgentManagement location and find the msi. When I tried to install that msi package, I received an error that the â€œthis installation package is not supported by this processor type.â€ The host is running AMD64 Windows, and the file came from the AMD64 part of the AgentManagement tree.
I checked the list of installed apps on another x64 DC, and saw that the â€œSystem CenterManagement Pack Helper Objectsâ€ item had been installed. So I tried repairing the agent install from within Ops Manager. Error persists.
Checking the hotfixes required to make Ops Manager agent work on Server 2008, and they are missing. Stay tunedâ€¦
Applied the hotfixes and still no love. I did dig into the eventlog, and saw that it appear the ADDiscover script failed in some way. I tried running the script manually (using the arguments from the eventlog entry), but it still failed. I fell back to google and found the following promising KB article: Alerts are issued from the MOM Active Directory Management Pack after you install an Operations Manager 2007 SP1 agent over a MOM 2005 agent on a domain controller that is running a 64-bit version of Windows.
Now this KB article describes a set of circumstances that donâ€™t match my situation. I didnâ€™t install MOM 2005 agent and then the OpsMgr 2007 agent on the same host. This system was built from the ground up with server 2008 x64 and Operations Manager 2007 was deployed here way before server 2008. However, the constellation of symptoms and architecture issues make it sound interesting.
Just found Kevin Holmanâ€™s blog and his list of hotfixes. I must go read about these and OpsMgr SP2 before doing anything drastic. Nothing like breaking the server late on a Fridayâ€¦
