I have a Windows 2003 Server with an extended partitioned disk that is located on a SAN. I can expand the disk on the SAN, allowing the added space to show up as "Unallocated" space at the end of the disk in Disk Management, but when I try to use diskpart to expand the extended partition to use the unallocated space, nothing happens. This procedure worked when using Windows Server 2000. Has the functionality of Diskpart changed in 2003? Can this be done with a 2003 server?
