By DA0 files do you mean System.da0 & User.da0? If this is the case, then as far as I know these are just the previous version of your System.dat & User.dat. They should be replaced when you restart Windows.
They may be difficult to find in Explorer as their attributes are set rhsa and will not show up unless you have told explorer to show all files.
If I remember rightly there was a utility on the 95 cd called Cfgback, but this had to be installed, and then run manually. I do not think there was any auto backup.
I think the only other way of recovering a corrupt registry was with attrib and ren commands, but this used the dao's, and if they've gone I think that's it. New ones should be created on each boot up though. Could it be that they are just hidden. If not then it seems that for some reason Windows is not producing them as it should.
No not a windup! I have been plauged by the notice that says Registry has encountered a problem.... then I have to say no and it starts but the notice appears again and again in the middle of the work you are doing, I discovered that the D0A files were missing, I used the Ontrack Utilities windows registry defragmenter and it worked fine for a few months, but now it does not appear to work. By using attrib... dos says D0A files cannot be found! I thought there would be a easier solution then re-installing windows. It certainly looks like that I have to reinstall windows, may switch over to win 98se, will have to buy one first. Many thanks for you kind support everyone. Jos.
