NOTE: The information contained in this article is provided for informational purposes only. Microsoft cannot guarantee Microsoft Networking functions Server Message Block (SMB) will work as expected when servers running SAMBA are present within the workgroup or domain.



SYMPTOMS
When browsing from one domain to another across a router you may receive a message saying "No domain server available..."

However, you can connect to shares on the primary domain controller (PDC) and even set up trusts.



CAUSE
Samba appears to force browser elections in a way that is incompatible with the normal Windows browser election process. That is, by issuing election criteria guaranteeing it will win the election and become the domain master browser. The IsDomainMaster registry setting still cannot force the Windows computer to be the master browser.

[From the Samba FAQ]

Samba is a suite of programs which work together to allow clients to access to a server's filespace and printers via the SMB (Server Message Block) protocol. Initially written for Unix, Samba now also runs on Netware, OS/2 and VMS.

In practice, this means that you can redirect disks and printers to Unix disks and printers from LAN Manager clients, Windows for Workgroups 3.11 clients, Windows NT and later clients, Linux clients and OS/2 clients. There is also a generic Unix client program supplied as part of the suite which allows Unix users to use an ftp-like interface to access filespace and printers on any other SMB servers. This gives the capability for these operating systems to behave much like a LAN Server or Windows NT Server or later machine, only with added functionality and flexibility designed to make life easier for administrators.

The components of the suite are (in summary):

smbd, the SMB server. This handles actual connections from clients, doing all the file, permission and username work

nmbd, the Netbios name server, which helps clients locate servers, doing the browsing work and managing domains as this capability is being built into Samba

smbclient, the Unix-hosted client program

smbrun, a little 'glue' program to help the server run external programs

testprns, a program to test server access to printers

testparms, a program to test the Samba configuration file for correctness

smb.conf, the Samba configuration file

smbprint, a sample script to allow a Unix host to use smbclient to print to an SMB server



RESOLUTION
Make the PDC the master browser. This can be verified with Browser Monitor.

This may require disabling Samba, the Samba computers, or moving these computers to another workgroup.
