Problems with Samba, can't see or mount shares

Hello,

I am running samba 3.06 on Mandrake 10.0. I can see shares with
smbclient but I am unable to mount shares or see them from my windows
computer. All of the other network services such as ssh ftp and http
apparently work fine.

When I attempt to mount shares on my Linux computer as a user with the
command "smbmnt Mark //localhost/homes" I do not get any error message.
When I cd to the directory that is mounted (mounting the share on the
directory "Mark") and try to ls the directory I get the message: "ls: .:
Input/output error"
The same thing happens when I issue the df command.
I can access the shares with smbclient with no apparent errors.

When I try to umount the share as user, it hangs for a while but does
not give any error message. But df reveals that the share is still
mounted. The only way that I can umount the share is by su ing and then
it will umount by issuing "umount /mount-point"

My smb.conf file is below. (With most of the comments deleted.) I also
tried the smb.conf file which worked fine on my Mandrake 9.0 machine,
but I got the same results. Can anyone offer some advice? I would like
to be able to access files and printers on my samba server from my
windows laptop

# A useful application of samba is to make a PDF-generation service
