Paul,
Your procedure worked great! I've logged on 5 times
since applying the fix, and the problem has not recurred.

>| My XP Home Ed. has several user accounts for logging
on.
>| One of them has problems pretty regularly (about every
>| 2nd or 3rd logon) where the logon attempt produces a
>| dialog box which states that the user's logon could
not
>| be performed, and the default logon for the system is
>| being used.
>|
>| The XP Event Viewer shows numerous error entries in
the
>| Application section related to these logon events.
There
>| are usually 2 events associated with the problem. The
>| event IDs are 1505 and 1508. Here is a typical
>| description from a 1508 entry:
>|
>| "Windows was unable to load the registry. This is
often
>| caused by insufficient memory or insufficient security
>| rights.
>|
>| DETAIL - The system has attempted to load or restore
a
>| file into the registry, but the specified file is not
in
>| a registry file format. for C:\Documents and
>| Settings\Dayna\Local Settings\Application
>| Data\Microsoft\Windows\\UsrClass.dat"
>|
>| The userid in trouble ("Dayna") has Adminstrator
rights,
>| and the machine has 256MB of RAM.
>|
>| Any ideas about what might be wrong and what can be
done
>| to correct the problem?
>|
>| Thanks....Steve
