To all, I am hoping that someone can give a lead or answer to my problem. I have two RH linux servers with 2.2.16 kernal and kimberlite failover. Both are configed using Samba 2.07. The smb.conf file is in the cluster directory so that both servers read one conf file. Locks and log files are on shared disk space. What I am seeing is this. Occasionally, and sometimes after failover, my Samba shares become inaccessible to clients that have had drive mappings made. Initially the mappings work fine, then, the user gets a error that the network name is no longer valid. If I create a new share or recreate an existing share, the user is fine. I can even create a new share below the current one and the user can map to the new one but not the existing one. Also, this is not a general occurrence as I can go to a different Win box, in the same and different subnets, and access the existing shares. I have not seen this on a RH linux server with the same kernal and Samba but not in failover. Cannot say if that is the problem piece but I am looking as to why that might cause a problem. Can anyone answer or at least point me in a good direction? I'm about to break out my sniffer and start looking at packets.
