I'm sorry, but you all seem to misunderstand.
XP appears to be working somewhat fine.
It is ntbackup.exe that is not working. I see it in the Task Manager, and
when I Debug the task, I see it stalled at an "int 3" instruction, indicating
it encountered some kind of exception.
I would like to be able to use ntbackup to create disaster recovery backup
on a separate disk.
The reason I want to do this that I want to use the XP install disk to
repair XP. The reasons for that are the errors I am seeing in event viewer.
1. LoadUserProfile errors in Event Viewer when booting. I had a couple of
users that I have deleted, and I fear that the deletions left some corruption
in the hive.
2. The Aministrator account is visible from Computer->Manage->"Local Users
and Groups"->Users, and there is a folder for Administrator in "Documents and
Settings", but the Administrator account does not appear on the Windows Logon
screen.
3. Occasionally, I see DNS and AVG update services leave timeout errors,
though they do restart on their own.
4. I have enjoyed several blue screens with stop code 19.
Basically, I have some hive corruption that I'd like to clean up with the
Restore facility on my XP disk.
HOWEVER, the Restore procedure described in
http://support.microsoft.com/kb/315341/en-us STRONGLY suggests that you use
ntbackup to save the current hive in case the Repair goes awry, so you will
at least have something to recover from.
As annoying as the long bootup times are, and as disconcerting as the
somwhat rare blue screen is from time to time, I would like to be able to
stabilize the system if possible.
