OpenE running Samba. Accessible from WinXP (for instance) no problem. Windows 2003/SP2 however, I fail with auth errors. I have network traces on both ends; connection is established no problem and the correct username passes over, but no joy in Mudville. I=92ve tried every combination of domain\user, user@domain, etc, I can think of. I=92ve already used secpol.msc to downgrade the NTLM level =96 none of them work. I=92m pretty much at the end of my rope here. =20 Humbly asking for a dummy=92s version of how to make this work. No virus found in this outgoing message. Checked by AVG.=20 Version: 7.5.524 / Virus Database: 269.23.4/1394 - Release Date: 4/23/2008 7:16 PM =20
