[Samba] XP SP2 client doesn't find netbios alias servers

[Sten Sletbak]

After upgrading XP to SP2, I can no longer connect to server aliases.
The client reports an error 53, "The network path was not found", when
doing "net use * \\prof\profile.
Mapping to a share on the real netbios name works fine.

Anyone else seen this?

Setup:

samba-3.0.6.rc2

smb.conf

[global]

netbios aliases = PROF
include = /etc/samba/smb.%L

smb.prof

[profile]
       path = /data/samba/profile
       csc policy = disable
       profile acls = yes
       read only = No
       create mask = 0600
       directory mask = 0700
       browseable = No

Here's a tethereal dump on the server of the client trying to map \\prof\profile.
