[Samba] XP Pro client cannot access stand-alone linux samba server

[Ian Colley]

Hi, I am trying to set up my internet connection sharing linux box as a 
stand-alone samba server.  When i try to access the server from a 
Windows XP Pro client using \\192.168.0.1 i get a dialog box asking for 
a username and password.  I duly enter this and the dialog box 
immediately re-appears without connecting me to the share.  There exists 
both a samba and linux account with the same password which is also the 
same as the XP Pro logon.

The XP Pro box is not set up to logon to a domain, both of the boxes are 
on the same workgroup.  I can get samba to work using share-level 
security but only for a guest account.

Would appreciate any suggestions

*smb.conf*
[global]
workgroup = WORKGROUP
netbios name = SAMBA
server string = Samba server in user level
security = users
encrypt passwords = yes
