XP64 - My Computer & send-to menus freeze

I am working on a bunch of systems for a client. They all share the same problem:

When I open 'my computer' on this XP64 system, it takes about 3 minutes before it displays anything in the window. The same delay occurs when I right click on a file & touch the 'send to'. I dissabled all network drives. I also removed everything from the "send to" menu. But this did not help at all.

I cloned the drive onto another disc...when I removed the old drive & booted from the new drive, it lost the problem...so I low formated the problem drive & cloned back onto it. This fixed the problem.

Anyone have any idea how I can fix the other 12 systems with this same problem? (without spending eight hours on each machine)

[edit[

Nevermind. I had to re-do all of them the long way.
