SYMPTOMS
A memory leak occurs when you use the Virtual Disk Service (VDS) framework to extend a volume in a loop in Windows Server 2003. When you view the Processes tab in Task Manager, you see that one or more of the following processes consume lots of memory:
 * Diskpart.exe
 * Dmadmin.exe
 * Vds.exe

Additionally, when you perform a disk-partitioning operation, that operation may be very slow, or it may not work at all. The memory leak eventually causes the volume to stop responding.
