I am running CentOS 5.3 (2.6.18-128.1.1.el5) - all based on Red Hat.
I have configured Samba as PDC, but my Windows Client, Vista Business, cannot join the domain, I configured in Samba. It tells me, that the RPC server is not available. Google tells me, that many have the same problem, but a solution doesn't exist, obviously. Who wants to try?
