Create a BDC (backup domain controller), any old system will do from the
sounds of it (if you onyl have one PDC and no BDC's then your network
probably isn't to large), attach it to the network, it will sync with the
PDC, you now have a copy of all accounts/passwords, you may need to manually
copy profiles/etc/etc, do so. Then unplug the PDC, and promote the BDC to a
PDC. Voila. A new clean PDC. Repeat as needed if you want to swap the old
PDC back in, but this may be a good excuse to get a new server for the PDC.
Plus this leaves the old PDC for forensics examination.

You may also want to enable a lot more logging in future and have windows
auto-update installed, as well as an anti-virus package etc, etc.
