NW5.1 & Legato Client 4.15

Hello,
I have installed NW5.1 SP2a and Legato Client V4.15 in a new Tree.
If I start the Legato Client (networkr.ncf) they can’t see the Backup Master Server (Unix Roboter)
(Message: Server or RPC not found).
Also if if I like to search a BackupServer, they don’t see it. The ping (IP Adress and Hostname) to the Backupmaster is OK!

I hahe installed the same Legato client 4.15 on
the older Tree on a NW4.11 server with no problem!

There not much info’s on Legato Webside.

Does anybody know about the Problem Server not
found? Does this work on Nw51 sp2a?

Thanks!!!!!!!!!!!!!!
