When you say it disconnects, what exactly is happening?

In my experience, unless the hardware platforms are EXACTLY the same,
this will not work. Too many drivers are loaded and configured during
the OS install that are specific to the hardware present at the time.
Granted, Kudzu will try to detect and install new drivers for new
devices, but I don't think it will be able to handle a wholesale swap
of your hardware environment.

Why not do a clean install on the new hardware?

Again, it is more than changing from a 64 bit system to a 32 bit. It
sounds like all of the hardware (Hard Drive controllers, video card,
etc) will be different as well. These present just as much of a

Look at some things before and during the next "disconnect":
- ifconfig How many Tx and Rx errors before disconnect? How many
after? If the numbers jump, look at replacing the network cabling
(since you have swapped the Ethernet card and Switch already).
- top What is the normal load on the server before disconnect? What
is the load when it actually disconnects?
- do some streaming media to the server. Does it disconnect when you
observe the other symptoms?
More information about what you are calling "disconnect" might help.
