During agent push installation, Microsoft System Center Operations Manager 2007 tries to read the PROCESSOR_ARCHITECTURE environment variable to determine what agent (x32 or x64) should be installed. However, when the PATH environment variable is over 1,024 characters, agent push installation fails, and you receive the following error message:
The MOM Server could not execute WMI Query "Select * from Win32_Environment where NAME='PROCESSOR_ARCHITECTURE'" on computer servername.domain.com. Operation: Agent Install Install account: Domain\username Error Code: 80004005 Error Description: Unspecified error
To resolve this problem, install the hotfix that is described in the following Microsoft Knowledge Base article:
950681 On a Windows Server 2003-based computer, the Win32_Environment WMI class does not return the value of the PATH environment variable if the variable contains more than 1,024 characters
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
