'not accessible' + ' The parameter is incorrect' when tried to access symbolic link path.

Unable to access the symbolic link, created from mklink for a Volume shadow copy.

I tried to create a persistent VSS copy with :

[1] c:\vshadow -p D:

     After creation of the persistent VSS copy, I created a symbolic link :

[2] C:\tools>mklink /d c:\vss_new \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy13

     symbolic link created for c:\vss_new <<===>> \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy13

Now, If I try to access c:\vss_new, I am not able to access and get error as 'not accessible' and 'The parameter is incorrect' message. 

I tried programatically also, i.e through CreateSymbolicLink() and I get the same behaviour.

Please let me know, if anybody has experienced differently. This is on Win 7 64 Bit.
