Insufficient Privilege Error with Remote Command Execute
This response is coming from the target server, which replies back to OO with a ReturnValue of 3 - Insufficient Privileges.
Please try the steps below to check the target machine settings:
1. On the target machine, run "gpedit.msc" and then navigate to:
Computer Configuration/Windows Settings/Security Settings/Local Policies/User Rights Assignments
2. Look for "Replace a process level token" and add the following account to the list if they are not listed.
3. Check if the issue was resolved.
Please keep in mind, that you need to reboot the machine for the changes to take effect, a Reload off the Security Settings won't make the changes immediately active!
Hope this helps!
