Symptoms
- Windows built-in Administrator was renamed to a different name and does not exist at Computer Management > Local Users and Groups > Users.
- When restarting any service via Plesk Services Monitor, the operation fails with the following error message in a popup window:
QuoteAccess is denied. (Error code 5) at Unable to connect to pipe \\.\pipe\P_047a9f38-4df5-807f-33791b74c301
at (Con::ClientOverlappedPipe::create line 503)
at get shared instance of PleskSrcClient(PleskSrvClient::getInstance line 334)
at Execute --start-plesk-website(execPleskUtil line 111)
- When running any Plesk utility in a command prompt, the following error message appears:
c:\>plesk version
Access is deniedCause
Plesk requires Windows built-in Administrator to work properly.
Resolution
Recreate the Administrator user by renaming it back or creating a new one with all required privileges and groups.
