I built a Server 2003 R2 VHD with MOSS on it and it runs fine on my machine.  
I gave a copy of the vhd and vmc files to a colleage who wants to explore a
little MOSS development and everytime he tries to start the VPC, the Server
2003 gets part way through the start up and then reboots

he did a new virtual machine from an Existing Virutal Hard Disk and also
tried Adding an Existing VM from the vmc file.

Either way, Windows Server (in the VM) just keeps rebooting.

Any ideas?

I had one experience like that from a zipped copy.  I never got it to run
when I woke it up (unzipped) and had to do a new (unzipped) archive copy.

That's interesting.  VMPlayer/appliances had their fedora 9 zipped as "F7"
(something I had not seen before, though WinRAR hopped right on it).
It was collapsed by 80%.  I tried another VM this morning and regular RAR
collapsed it to 55%, and rar zip ('best' mode) could only manage about 42%.
I would have expected a variation due to data density but i felt that this
was more than expected.

Did you compact it first?

No I didnt compact it.  I can copy it as is to another directory on my
machine and create a new VM from it in that directory without compacting, but
I will compact it and have my buddy try again.

Thanks

Compacting is not the same as compressing (zipping).  I assume you know
that.  Compacting is not necessary but try avoiding compressing to see if
that resolves for you.

Yes, i realized that quickly with the google search on the subject.

Just as a test, I compressed (RAR) a Dos 6.22 VM last night, uncompressed
it, renamed the .vmc and .vhd and added it as a new VM under MS VPC 2007.

The VM and its applications worked fine.

I will probably continue the test with win 98 to get higher up the MS food
chain. I can understand defragging it first.

(Michael was the one who had the problem with compressing/decompressing
VMs.)

Compacting is the process of reducing the .vhd's size on the host by
elimating the excess file space no longer in use inside the vm but not yet
freed back to the host file system.  Basically you defrag inside the vm to
sort the free space, pre-compact with the .iso file for that provided with
VPC to zero out the free space, and then edit the .vhd with the Virtual
Machine Editor to remove the zeroed out free space on the host.  It doesn't
change the amount of disk space in use as seen by the OS in the vm but it
does release (sometimes a lot) of host file space.
