Today I downloaded cifs-1.0.2b and the latest mount.cifs, but it
doiesn't work, too. I get either a connection error:
Feb 19 09:53:36 merlin kernel: <3> CIFS VFS: Error -32 sending data on
socket to server.
Feb 19 09:53:36 merlin kernel: CIFS VFS: cifs_mount failed w/return

socket to server.

or a segfault:

dereference at virtual address 00000000

I really need this stuff to connect to a W2K3 server!
Again: Any help would be greatly appreciated! If you have another
workaround (even without cifs) it would be welcome!
Thanks in advance!

P.S. please CC any answers directly to me, cause I'm not subscribed to
