I'm trying to setup network shares on an XP Pro sp2 machine. I had sp3 installed and
removed it because an IBM program wouldn't run in sp3.

I'm trying to share a folder called scans on an AS/400. The AS/400 netshares is
configured to share the folder with unlimited users. The user allowed to share the
folder on the AS/400 is called scans. The user scans is created in XP Pro.

Both computers have the same user name called scans and the same password.

The user scans on the AS/400 is enabled.

Both computers are set with a workgroup called Workgroup.

In XP Pro the:

computer browser has been restarted.

Net Logon is not started and set to manual.

If I go into Windows Explorer, My Network Places, Entire Network, Microsoft Windows
Network, Workgroup, ATU1277

It asks me for a user name and a password.

If I put in user name:scans password:MyPassword

The username/password screen comes right back. Over and Over again

The firewall on the XP machine has TCP ports 137, 138, 139, 445 open.

The firewall on the XP machine has 192.168.1.1 Trusted. This is the machine called
ATU1277.

I have "simple file sharing" un-checked.

I have also tried net use L: \\192.168.1.1\SCANS /user:192.168.1.1\administrator

with the administrator password for the XP machine.

I have tried turning File and Printer Sharing for Microsoft Networks off, Ok, On, Ok.

Does anyone have any ideas what I might try next?

Thanks,
