By connecting a single host or VC with VI Client I receive this error: “The requested operation is not implemented by the server”
My Virtual Infrastructure Client is configured with PassThroughAuth parameter set for Auto SignOn capabilities. With parameters: "D:\APPS\VMware\Infrastructure\Virtual Infrastructure Client\Launcher\VpxClient.exe" -passthroughauth -s localhost
Solution: Use the Shortcut in your Menu Start > VMware > “VMware Infrastructure Client” of delete the passthroughauth parameter in the shortcut/target field.
Now I can connect my VC/Host with the VI Client without problems.
