Hi Thanks
That's no problem, we'll do the replication of the data. What we'd like
is what windows has. You can specify \\domain\dfs\share and it finds a
server in the domain with the share. Really easy. I suppose it's a
nightmare to code though, if it can be done at all. Do we have anything
like that in samba?
Cheers,
Steve
