You can use Windows 2000 Group Policy objects (GPOs) to assign .msi packages to a group of Windows 2000 Professional-based workstations based on their membership in an organizational unit. When a workstation is rebooted and the computer policies are applied, the assigned programs may not be installed and the following error messages may be logged in the Application event log on the Windows 2000 Professional-based workstation:
Source: UserEnv Event ID 1000 The Group Policy client-side extension Application Management was passed flags (1) and returned a failure status code of (1612).
Source: Application Management Event ID 108 Failed to apply changes to software installation settings. Software changes could not be applied. A previous log entry with details should exist. The error was The installation source for this product is not available. Verify that the source exists and that you can access it.
Source: Application Management Event ID 303 The removal of the assignment of application "Package Name" from policy "Policy Name" succeeded.
Source: Application Management Event ID 102 The install of application "Package Name" from policy "Policy Name" failed. The error was The installation source for this product is not available. Verify that the source exists and that you can access it.
The machine account for the workstation does not have permissions to the share or file system that holds the source files for the package. When a workstation runs Group Policy, it does so in the context of the machine system account for the workstation.
Confirm that the machine account for the workstation that is applying Group Policy has at least Read access to the source files for the package that is assigned with Group Policy. You can do this by assigning permissions directly to the machine accounts, or by assigning permissions to a Security group, such as the Domain Computers or Authenticated Users group that contains the machine account.
If the source files are located on a Distributed File System (DFS) share, confirm that the machine account has sufficient NTFS and share permissions on all root replicas of the DFS root, and on all replica shares of the DFS link.
This behavior is by design
