For an issue I worked on, the application pool kept stopping with Event ID 2269, 5139, and 5002. The errors and warnings I saw in Event Viewer are below.
Check if the application pool identity has “Bypass traverse checking” permission. This is group-policy permission to determine which users can traverse folders even if they don’t have permission on folders.
To give “Bypass traverse checking” permission:
- Go to “Start > Run”, type “gpedit.msc”
- Follow “Computer Configuration > Windows Settings > Security Settings > Local Policies > User Rights Assignment”
- Right click “Bypass traverse checking” and click “Properties”
- Click “Add User or Group”. Add these users and groups: Everyone, Users, IIS_IUSRS, IIS AppPool\DefaultAppPool
- Restart the server
- Open the same window and make sure the users/groups you added are still there
- Test the application
If this doesn’t work, use “netstat” and see if there are port conflicts. There might be network and file structure related issues as well
Note: With the steps above, we added more users than we should. This is for testing only. You can later harden this configuration.
