Hi Folks: It seems that there is a problem with samba and Server 2003 SP1. When SP1 Installs, samba stops authenticating in ADS mode, and causes considerable heartburn. The research that I have found (dated April of this year) seems to indicate that it is a problem with samba communicating with the Kerbros server using a protocol called schannel (I hope im getting this straight, Our domain controller crashed, and I have lost my history to go back to the sources that I found). Is there a work around other than not using SP1, I seem to remember that one of the sources that I saw indicated a command to be included in the smb.conf file, but I cannot find it readily. Can someone please enlighten me as to how to get this working??? Thank you so much for your time and trouble TIM
