samba?

How are you trying to access the folders?

I use smbmount with options for user and password and can mount and see and access windows shares OK.

Make sure that your user is authorized to access the folders

ya you must need samba2.2 if you have workgourp environment or 3.0 if you have domain environment

now you must have to create your windows useraccount into samba and assign it the group which your account is form as in windows, like admin user poweruser etc...

then you must be able to access the others resources from the username and password you have just give in samba

well you have define or enable guest account in samba so thats why others can access your resources you must create your useraccount in samba resembles that you were using in windows environment as i mention above to access other users resource.

how r u accesing windows system. u can mount that system by

mount -t smbfs -o username=xxxxx //192.x.x.x/yy /home/zz

where 192.x.x.x is the windows system IP. yy is the shared folder or path onm windows system and zz is ur /home/zz is ur local syystem path where u would like to mount that remote directory. i hope this will work for u.
