Parallels Management Console (PMC) is installed on Windows 2008. It is not possible to connect to a Virtuozzo Container on the localhost. It fails with this error: Code 422: Named Pipe connection failed, error #5[Access is denied.]


Disable User Account Control (UAC) on the server. It prevents PMC functionality. Please note that after disabling UAC, a reboot is required.

If disabling UAC is not possible, it is necessary to change the privilege level of the PMC. Change the properties of the PMC startup file (Properties -> Compatibility tab -> Privilege level -> check "Run this program as administrator"). Save the changes. This will allow you to run PMC with administrators' permissions.
