I have a friend on the same network as me hosting a virtual machine using vmware server.The guest OS is Windows 7 and Windows Server 2003.He granted me administrative priveleges for the machine but when i try to add a user to that VM it says access denied.

Moreover when i try to start the VM remotely using the command

vmrun -T server -h https://computer-name.domain.com:8333/sdk -u domain/user -p passwd start "[standard] Win2k3Client1/Win2k3Client1.vmx"

This shows unsufficient priveleges on host operating system but i am able to login with same username password on VMWare Web Access
