[Samba] Mount Shared directory in Win2k

[hai wu]

I need to mount a shared folder in win2k, which is in a domain named dom1.
The permission of the shared folder allows 'user1' access with password
'passwd1'. 

In the manual of 'smbmount', it says:
I can use command like "smbmount username=user1/workgroup%passwd1", but my
question is:
Can I use command like "smbmount username=user1/dom1%passwd1" ?

That is, can i use domain name instead of workgroup name? If not, how can
I mount a shared folder with username & password(in a domain)?

Thanks,
Hai
