DG005
DG005 - This verifies if the /etc/passwd file contains an entry for agsadmin and agsuser. These OS users are created by the ArcGIS Server setup at the time of install, if they didn't exist before the install. Without these users, ArcGIS Server won't function properly.
If your setup was successful and these two users were deleted later on, you can create these two users manually to check if ArcGIS Server functions. If you still have problems, there is likely other damage to ArcGIS Server. A reinstall is recommended.
Example:
DG005 - check /etc/passwd: user agsadmin
DG005 - check /etc/passwd: user agsuser
