Sorry for the slight necromancy, but I have the same problem. I can't seem to mount windows shares either. Installing the samba mydsl extension didn't help. win 2k doesn't allow browsing such as network neighborhood/linneighborhood uses. I'm perfectly comfortable on the commandline, wasn't really even interested in the neighborhood icon.
I use the following command (credentials and such removed of course) on my debian box to mount windows shares:
Code Sample
mount -t smbfs -o username=validusername,password=validpassword //computername/sharename /path/to/mountpoint
This is of course the format smbmount tells me to use, but why does it not work on DSL?
