Using Samba, RH9.0 all users belong to one group (users) and one person (Admin), yet when users access their files the file flips over to read only. Permission level is set to 777 and a chmod will set straight but how do I prevent this from happening?

are you exporting a smb share from linux? if so, make sure that it is exporting as RW.

Not sure I follow the "exporting" the share is available on the linux box, how do I make sure its RW?

what I mean by exporting is: do you make your linux filesystem available to remote machines using smb?

so are you trying to use windows to connect to a linux filesystem? i believe that samba assigns its own permissions, so if you chmod a file the settings won't be necessarily be reflected in samba (i could be wrong tho).

I think what you have to do is modify your current config. either through the samba web-based config or by hand.

check out the howto at:
http://www.tldp.org/HOWTO/SMB-HOWTO.html

it is fairly old but probably still relevant.

Or if you are trying to access a windows filesystem from linux, then check the settings on the windows box and make sure you are mounting the filesystem with an appropriate user, ie:
mount -t smbfs -o username=yourusername ....
