I've had this same problem from time to time and since upgrading to 
Fedora 10 it has come back:
Fedora 10 - kernel 2.6.27.21-170.2.56.fc10.i686.PAE
autofs-5.0.3-41.i386

The correctly mounted manual entry:
//xp0/C$ on /mnt type cifs (rw,mand)

The autofs entry:
//xp0/C/$ on /smb/xp0/C$ type cifs (rw,mand)

If you need anymore debug info let me know
