Hi All,
Due to a hard-disc crash, I have just upgraded from a working Samba setup
running in FC2 to a non-functional Samba setup running in FC3.  The Windows
XP machine has not changed, but won't connect.  Samba is fully up2date
from the FC3 repositories.
smb.conf
   [global]
   workgroup = MYGROUP
   server string = Samba Server
   hosts deny = ALL
   hosts allow = 192.168.1.0/24 127.
   interfaces = eth0 lo
   printcap name = /etc/printcap
   load printers = yes
   cups options = raw
   log file = /var/log/samba/%m.log
   max log size = 50
   security = user
   socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
   domain master = yes 
   preferred master = yes
   dns proxy = no 
   idmap uid = 16777216-33554431
   idmap gid = 16777216-33554431
   template shell = /bin/false
   winbind use default domain = no
   [homes]
   comment = Home Directories
   browseable = no
   writable = yes
   [printers]
   comment = All Printers
   path = /var/spool/samba
   browseable = no
   guest ok = yes
   writable = no
   printable = yes
   [share]
   comment = Shared filespace
   path = /share
   read only = no
   public = yes
   [tmp]
   comment = Temporary file space
   path = /tmp
   read only = no
   public = yes
Following through the tests in the diagnosis section of the on-line manual:
Test 1: testparm is happy
Test 2: client and server can ping each other; 
   /etc/hosts.deny
   ALL:ALL
   /etc/hosts.allow
   ALL:83.104.103.142
   ALL:192.168.1.0/255.255.255.0
   No iptables
Test 3: expected output, but a password is required
   [root@purse samba]# smbclient -L PURSE
   Password:
   Anonymous login successful

           ---------            -------
           MYGROUP              PURSE
Test 4: seems OK
   [root@purse samba]# nmblookup -B PURSE __SAMBA__
   querying __SAMBA__ on 192.168.1.10
   192.168.1.10 __SAMBA__<00>
Test 5: doesn't work
   [root@purse samba]# nmblookup -B FAX '*'
   querying * on 192.168.1.7
   name_query failed to find name *
Test 6: doesn't exactly work
   [root@purse samba]# nmblookup -d 2 '*'
   added interface ip=192.168.1.10 bcast=192.168.1.11 nmask=255.255.255.254
   added interface ip=127.0.0.1 bcast=127.255.255.255 nmask=255.0.0.0
   querying * on 192.168.1.11
   querying * on 127.255.255.255
   Got a positive name query response from 127.0.0.1 ( 192.168.1.10 )
   192.168.1.10 *<00>
Test 7: works
   [root@purse samba]# smbclient //PURSE/TMP
   Password:
   Anonymous login successful
   Domain=[MYGROUP] OS=[Unix] Server=[Samba 3.0.10-1.fc3]
   smb: \>
Test 8: fails completely
   C:\\Documents and Settings\jonathan\> net view \\purse
   System error 5 has occurred.
   Access is denied.
How do I move forward ?
