I am running SUSE ES9 on a Dell PE Server. I have set a common folder to be shared from all machines on the LAN via Samba. All the XP Pro machines can see it in the network neighborhood but I have just mapped the folder as a drive on the Windows machines so it is easily accesable from "my computer".
Our lone Windows 2000 machine can also see it but not access it either from NN or as a mapped drive. If you click on it, the machine simply hangs for a few seconds. These machines can ping each other and no firewall is in place. The Windows 2000 machine was not set up with a login or password (not my doing) but neither are any of the XP machines.
All the posts I have found on the Internet deal with machines that either cannot even see the Samba machine or have login failure but not the problem I am having. I have added no users to Samba but again none of the XP machines seem to have any issue with it. Samba asks for a user ID and password when the XP machines first connect and I used the same ones that I use to login the Suse machine with. I just clicked "remember password" and "reconnect on startup" and it seems to work fine.
On a curious note I did have a similar issue on a Windows ME machine I was experimenting with. It would ask for a password only and not a login so it too would fail. I tried making a profile on the Win Me machine with no joy.
