Hi Angus, I am not sure that this will work. I think you might have to install the service pack and all patches after the clean installation to have a successful restore. But there is only one way to be really sure: Try it out! I don't trust my backups until I have successfully tested a full restore.......

I have a number of remote W2K domain controllers at the far end of slowish wan links. I use NT Backup to backup the system state locally every night, compress the .bkf to a .zip file and copy the zip files onto my NAS during the small hours. If I had to rebuild a server, could I simply reinstall a basic W2K server, then restore the system state. Would SPs be maintained or would I have to apply the proper SP before doing the restore?
