Please extract the descriptor from "E:\win2k32\Windows Server 2003 Enterprise Edition2" too and attach it to a reply post. The file is a .vmdk file but the file extension is missing (don't rename it!!!)
According to the snapshot chain, the "Windows Server 2003 Enterprise Edition.vmdk" file has been modified (most likely because you started a VM with the .vmdk files attached) and the snapshot chain doesn't match anymore. Do you have a backup of this file which contains "CID=8a0c5dd4" in the descriptor?
Due to the monolithic file format you use, it's not possible to delete/merge the snapshots - at least for the large data disk - without additional disk space. Do you have another disk with at least ~260GB free disk space? I think the most straight forward way to resolve this issue is to manually clone the virtual disks (including the snapshots).
Once I have all information I can guide you through the required steps.
