Hi, I have a samba 3.0.20 as domain master browser of a Windows network. Sometimes, the Windows workstations are getting a error: "Windows cannot connect to the domain, either because the domain controller is down or otherwise unavailable, or because your computer account was not found". I was trying to change the RequireSignOrSeal register value of the windows workstations, but this didn't work. Looking for a error on the logs of windows workstation with this problem, I can see a worstation trying to connect in other workstation, and it not on server. The server is ok, the "os level" is 100. I can't find log messages of this workstation trying to be the domain master. How can I fix this problem? This error occur with some users, and this is a problem for me. Edgar
