I am running into a strange SAMBA problem that I am hoping someone else can shed some light on. My server is running CENTOS 4.5 with SAMBA installed and operating correctly. I can share a volume on the server and connect via a Windows XP workstaion, and share a volume on the Windows XP workstation and mount it to the Linux server..no problems. I have a device (a bill counter) at a client site that I must connect to and collect data files for processing. I was told that it was a Windows server, so I assumed that there should not be a problem. When the client had the device delivered and installed, I then go to look at the system and found that it acutally was not Windows but the old MS-DOS TCP-IP, similar to Windows for Workgroups. The bill counter has a share set up, and I am able to connect to it from a Windows workstation with no problem..no password required. However, I am unable to connect from the Linux server to the bill counter. I've tried all types of incantations, but to no avail, I continue to get a RAP143 error, a search of which did not lead me anywhere useful. Is there anyone out that that can give me some ideas on what to try. I am afraid that the operating system of the counter is the problem, ie MS-DOS TCP/IP but the fact that the client can connect a windows workstation to it has made it difficult. thanks in advance.. dave
