I've got an old (built approximately four years ago) Shuttle SN45G
which I've just booted up after it being left in storage for a few
months. On the first boot I found that all the BIOS settings had been
erased/forgotten, so I reconfigured them all and everything worked
fine. However, if I power down the machine and disconnect it from the
mains all the settings are erased again (this doesn't happen if I just
switch off the machine, only if I disconnect it from the mains power
supply as well).

I'm guessing the battery on the motherboard might have gone - is this
likely to be the case? If so, is it easy to source and replace new
batteries?,

(I'm running Windows 2000 with all the relevant drivers, though I
don't think the OS is the cause of the problem).

Thanks in advance for any help/pointers.

I should add that I haven't updated the BIOS at any point, nor have I
disconnected the machine from the mains until it has fully shutdown
and powered off.

Replace the battery.

IMHO the battery theory is 99%+ certain to be the correct one. It has
always worked out that way for me.

As for the battery type, it is called out in your manual. Probably a CR2032
since this is the most common in modern motherboards. It should be dead
simple to replace.

Thanks, I thought it would be the battery but I haven't prodded about
inside a machine for a long time. I can't find the battery on the
motherboard so I guess I'll have to dredge through the manual,
assuming it's still available online.
