Hi I have a PDC server version samba-3.2.8-0.27.fc10.i386.rpm serving mostly Win98 machines after adding the following two lines managed to get it working with authentication and logon.bat scripts. /etc/samba/smb.conf lanman auth = Yes ntlm auth = No Now I want to add some XPPro machines but they can no not see server shares any more ( used to work on Fedora 5 server ) I have tried adding with some success. include = /etc/samba/smb.conf.%a smb.conf.WinXP Also do I need winbind /etc/nsswitch.conf hosts: files wins dns nis ldap NOTE: I have a BDC and trying to get ldap working but disabled for now. Incidently a Vista machine works fine can I modify all the winxp machines in the registry to get them working as well. And I get samba.__ffff_192.168.1.28 in the logs I have tried disabling ipv6 but perhaps somehow it is still enabled and causing me problems somehow. Also when the clients try to use the Fedora 10 server often it seems a lot slower than Fedora 5 even though the server is more powerfull.
