 "\??\"  may be the cause (\\?\ is well documented not \??\). But I
wonder why junction.exe jucntion work just fine on our tests system (xp
and 2k3). Thanks for testing, I go back to code&test.

From my testing, this snapshot works for directory junction points
created with mklink. However still no go on mounted volumes or directory
junction points created with junction.exe.

Re-creating any faulting junctions with mklink seems like a good
workaround, but mounted volumes are still left in the cold.

Looking at the output of the dir command, the only visible difference
between mklink and junction.exe is the prepended "\??\", which is also
present on mounted volumes by necessity. 

Full test log follows:

C:\mnt\test>dir
 Volume in drive C is coreI7_System
 Volume Serial Number is 38E2-2B62

 Directory of C:\mnt\test
