[Samba] Windows XP & greyed-out Guest user password prompt
Hi, we've been using Samba for a while, and are just now starting to 
switch our desktop computers to Windows XP. We are having a problem 
where connections to our Samba server fail, and the user is presented 
with a password prompt asking for a password for user Guest. They can't 
select a different user.
I've searched the Microsoft knowledgebase, and the Samba list archives, 
and there are others who have seen this problem, but none of the 
suggestions presented seem to help. We are currently using "security = 
share" because there are some legacy scripts that depend on not getting 
prompted for a username to access some read-only shares we have set up. 
But just for troubleshooting, I have tried setting "security = user"
and
"map to guest = Bad User" but XP still presents the guest password 
prompt and the user still isn't allowed to specify their username. We 
are not using a domain controller.
Everything works great when using a Windows 2000 client. In XP, mapping 
a drive to the Samba share works fine. From XP's command prompt, if the 
user's Windows login and password match what's in our LDAP directory 
(and they usually do), it lets them right in -- the user doesn't even 
get a password dialog when they do this:
"net use \\fileserver.example.com\share /user:joebob" But if you just 
set up a shortcut to \\fileserver.example.com\share or if you try to 
connect from the "run" line, it fails & tries to force them to
login
with the guest account.
If anyone has any suggestions, or can even make a guess at an 
explanation for this behavior, I'd really appreciate it.
Thanks!

[Samba] Windows XP & greyed-out Guest user password prompt
(replying to self) I'd appreciate any response at all (including RTFM, but a pointer to which FM I should R again would be very appreciated). Again, we're running Samba 3.0.7 on Debian Sarge, and this problem doesn't appear when we connect to Windows file servers, so I thought someone here might have some information that might help me track down the solution.

I have a samba server with a guest share, the only difference i can see is that i have guest only = yes. Here is one of the read only shares (sanitised): [guests] path = /guest/share guest only = Yes guest ok = Yes This works fine from XPSP2 and SP1 clients, the server is security = domain though, so this may make a difference, although non-domain machines/users connect with no problems to the guest shares.
