I found that Proxy ARP is enabled by default in Cisco IOS. See URL:

Hi guys,
As an IT professional who supports two schools (one K-12, one vocational center), I have to say I generally agree with Matt’s take on teachers. Occasionally you get a some good ones, but I find many to be somewhat lazy technophobes.
As for Linksys/Cisco – Cisco did announce that they were dropping the Linksys brand, and promptly backpedaled when they realized that this would be a huge marketing blunder.
Also, I love hearing your rant episodes. It’s sort of a vicarious venting for me because we have so many similar gripes with service providers and hardware vendors.
Keep up the good work!
Peter

The reason you had Virtual hard drive corruption was because the filesystem that held the .vhd did not support concurrent access. If more than one system was to see the same .vhd, then the file system that holds the .vhds needs to be filesystem that can handle multiple simultaneous access.
I believe that such a filesystem is called a “cluster” filesystem, and while Linux has ‘Oracle’s Cluster Filesystem 2 (OCFS2)’ in the kernel, and Redhat has their “Global File System (GFS)” and VMWare has their “Virtual Machine File System (VMFS)”, Microsoft’s plain-old NTFS can’t do it… unless you install Microsoft Cluster Services.
If the filesystem was plain old NTFS, then as soon as one of the vhds grew, the machines would have an inconsistent view of the free space; the other machine would still think that space was free.
I’m surprised it ran as long as it did.

Sorry I didn’t find this link earlier:
http://en.wikipedia.org/wiki/List_of_file_systems#Shared_disk_file_systems
There they call them “Shared disk file systems” and had one of those been used to hold your vhd files, you might still be up.
