Troubleshooting AGPM Upgrades
Try our Virtual Agent - It can help you quickly identify and fix common Group Policy Management issues.
This section lists common issues that you may encounter when you upgrade your Advanced Group Policy Management (AGPM) server to a newer version (e.g. AGPM 4.0 to AGPM 4.3). To diagnose issues not listed here, it may be helpful to view the Troubleshooting AGPM or for an AGPM Administrator (Full Control) to use logging and tracing. For more information, see Configure Logging and Tracing.
What problems are you having?
Failed to generate a HTML GPO difference report (Error code 80004003)
Cause: You have installed the AGPM upgrade package with an incorrect account.
Solution: You will need to be an AGPM administrator in order to fix this issue.
Ensure you know the username & password of your AGPM service account.
Log onto your AGPM server interactively as your AGPM service account.
- This is critically important, as the install will fail if you use a different account.
Shutdown the AGPM service.
Install the required hotfix.
Connect to AGPM using an AGPM client to test that your difference reports are now functioning.
