Server 2008 Extend Volume and Disk Drive size

Hello-

We're running ESX 3.5 and have a Server 2008 x64 Standard VM. We were trying to grow a data partition (primary partition; no issues with page files, system disk or anything) and Disk Management shows it as grown from 30GB -> 80GB, but the actual disk, D:\, still shows only the 30GB max size. We tried rebooting the VM and it stills only shows the max size of 30GB in the Explorer Window and trying to dump a 3GB file on there throws an error.

The VM itself has had its diskspace increased to 140GB, but is there anything else we need to do to get this to take or is this purely a MS problem? The VM is set as a single basic disc with 2 partitions (c and d).

Any thoughts suggestions?

Thanks.

Henrik
