On a computer that is running Terminal Services, when you try to use a push operation to install the Microsoft System Center Operations Manager 2007 Agent the operation may time out, therefore the System Center Operations Manager 2007 Agent is not installed successfully.

You may also receive an error message that resembles the following:

The MOM Server could not execute WMI Query "Select * from Win32_Environment where NAME='PROCESSOR_ARCHITECTURE'" on computer "computername".
Operation: Agent Install
Error Code: 80004005
Error Description: Unspecified error

If you're getting this error then we talk about it in a new Knowledge Base article we published last week:

KB978360 - A push installation of the Operations Manager 2007 agent on a computer that is running Terminal Services fails

Spoiler alert: The resolution is to install the agent manually, but at least the KB will give you some insight into why it may happen.
