Map network drive to a site url

[adamsharepoint]

Hello!

I have two top level sites:
1:

http://server/mySite

with many subsites
2:

http://server/sites

with many subsites

If I map a network drive to site 1 and open the drive
I can see all subsites, lists, document libraries and so on
as if it was a file system..

If mapping a network drive to site 2 the it just appears
empty. However if I type the exact path then it shows
the content..

Anyone having this problem or even better the solution ?
