Cannot connect to Mac OSX Snow Leopard client to back up

Installed Networker 7.6SP5 client on Max OSX 10.6.8 ("Snow Leopard"), cannot connect for backups or from Networker Console in the client config to list filesystems to select for backup.

Debugging attempt... turned firewall off on the Mac, it is in the same subnet as backup server, so no firewall between them.

Mac user reports:  "OK, firewall off, rebooted, firewall still off, Activity Monitor shows nsrexecd"

rpcinfo -p fails from backup server (Solaris 10 OS)

Tried on the Mac:

rpcinfo -p localhost     (works)

program vers proto port

  100000 2 tcp 111 portmapper

  100000 2 udp 111 portmapper

  390436 1 tcp 8335

  390435 1 tcp 9192

  390113 1 tcp 7937 nsrexecd

  100007 2 udp 606 ypbind

  100007 2 tcp 1020 ypbind

BUT, on the Mac still,

rpcinfo -p     (fails!)

rpcinfo: can't contact portmapper: RPC: Remote system error - Operation timed out

So, what else do we need to do to this Mac?
