Hello, I am running Samba 2.0.6 on a RedHat 6.2 computer. The Samba server is configured to validate the password on a Windows NT server with the "security=server" and "password server = <SERVER1 SERVER2 SERVER3>" directives. The Samba server worked well for quite a long time but this morning, the Samba server refuses to work. When I did my troubleshooting sequence, the command "smbclient -L <SAMBA SERVER>" gave me the following error message: protocol negotiation failed What does this error message mean ? Does it mean the Windows NT server has changed ? Upgraded ? or the Samba server was doing bad ? I changed the Samba server config file to validate the paswords locally and the system came back to work. I changed back the Samba server config file to validate passwords remotely but with a different sequence of Windows NT servers (i.e.: "password server = <SERVER2> <SERVER3> <SERVER1>") and the Samba server came back to work. Can somebody explain me this behavior ? Thanks a lot, Claude. -- Claude LeFran?ois, System and Network Administrator Ericsson Research Canada (LMC) 8300 D?carie, Ville Mont-Royal, Qu?bec, Canada, H4P 2P5 Tel: (514) 345-7900 x7579, Fax: (514) 345-6149 Email: lmcclef@lmc.ericsson.se -------------- next part -------------- HTML attachment scrubbed and removed
