mount_smbfs and MS Windows Domain Controllers

[Markus F. Meisinger]

Dear list,

if i try to mount a share on a Microsoft Windows 2003 Domain Controller
i get "Permission denied",
the password is correct,because if i use a wrong password i get
"Authentication error"
mounting shares from other Windows Workstations works fine.

for example
mount_smbfs -I 192.168.0.2 -W MK-MEISINGER //markus at frosch/library /mnt
192.168.0.2             ip of W2K3 domain controller
MK-MEISINGER             name of domain
markus            user of domain
frosch            W2K3 domain controller

i think i have to reconfigure the domain controller, but how?

Thanks for your help
Markus
