Infinitely Recursive Directory Problem

Folks-

I run Windows Vista/SP2 Home Premium on a DELL XPS1730 Laptop.

I have a problem which may be related to Windows being unable
to come up on my system following a DELL MEDIA DIRECT update.

I am using DOS command prompt RoboCopy to copy my files to a
backup device and have encounterd an infinitely recursive directory.

The directory in question is "C:\users\All Users". "All Users" is
not shown as either a hidden or unhidden directory so I assume this
is a result of a [junction] reference.

The copy proceeds as follows:

c:\users\All Users\Application Data\Adobe
c:\users\All users\Application Data\...(remaining directories)
c:\users\All Users\Application Data\Application Data\Adobe
c:\users\All users\Application Data\Application Data\...(remaining
directories)
c:\users\All Users\Application Data\Application Data\Application Data\Adobe
c:\users\All Users\Application Data\Application Data\Application
Data\...(remaining directories)
c:\users\All Users\Application Data\Application Data\Application
Data\Application Data\Adobe
c:\users\All Users\Application Data\Application Data\Application
Data\Application Data\...(remaining directories)
....etc
....etc

Is there a way to determine exactly what is triggering the recursive
directory loop and nullify it from the DOS command prompt? I'd like
to try something that might save me having to do a full system restore
and re-creation.

If there is no way to "fix" the existing directory structure does
it sound reasonable to copy the problem directory (16GB of directories
and files) with the "exclude directory junctions" parameter and then
replace the existing problem directory with the copy?
