I have a new VM running Server 2003. I am able to ping, get OS, get CPU, etc. just not Windows Updates. I checked the services in the tutorial, credentials, but still get the same error. I can’t even find a definition of the error “Error 1620: -1 Failure”.
1620 is a generic code in BatchPatch that essentially means that BatchPatch received an unknown/unexpected return code from the remote process. The batchpatchremoteagent.exe does not have a -1 return code, so this is likely an issue with psexec not being able to complete successfully. I would suggest going through the steps in the troubleshooting guide to test psexec without BatchPatch.
