Good Evening folks: I have a bit of a crisis here!!! My samba servers (2 of them) have been authenticating against my active directory server for a couple months with no problem. Suddenly today, they stopped working, and windows is asking for authentication and then not accepting it whenever I try to access a samba share. The only changes that I can see is that I applied a series of updates to the Active Directory server. The most likely culprit being the Windows 2003 Server Service pack 1 which I just removed. I will be removing the others shortly, however I am in desparate need of some help as our samba server is our file server and no one can get to any of their files (thank God it's the weekend). Any suggestions etc would be most appreciated TIM Timothy A. Holmes IT Manager / Webmaster / Computer Teacher Medina Christian Academy A Higher Standard... Jeremiah 33:3 Jeremiah 29:11 Esther 4:14
