What the heck is an error 2606? Why am I getting a 1612 prompt when I try to connect to the VMM Server from the Admin Console? Now you can look these errors up and review the Recommended Action.
The error codes are divided between 'User Interface Error Messages' and 'Command-Line Interface Error Messages'. User interface messages are understandable enough... You perform a P2V and the job errors out with an error message in the Admin Console. Command-Line, or CLI messages are those that appear in a PowerShell console when running scripts or performing interactive work.
