Hello List,

this is a connectivity issue between a NW Client (Name: su001, OS: HP-UX 11, NW 
7.1.1) and the NW Server (Name: legato, OS Win2000, NW 7.1).

If I try to backup su001 this fails with a connection timeout. I tried to 
figure out where the problem was. Basically it seems 'su001' cannot connect to 
the NW server 'legato'. Trying a manual backup from 'su001' fails because a 
connection to 'ntlegato' fails. 
But 'su001' can connect to the nsrexecd service on 'legato':

on 'legato': nsradmin -s su001 -p nsrexec is successful

on 'su001': nsradmin -s legato -p nsrexec is successful
                nsradmin -s legato -p nsrd      fails with error RPC error: 
Remote System Error - there does not appear to be a nsrd server running on 
legato
(BTW: nsrd service _is_ running on 'legato')

Why is it possible to contact the nsrexec service but not the nsrd service? I'd 
think they use same IP connection.
Is this a network connection issue or more likely NW related?

'su001' has two network interfaces. There is a firewall between the servers. 
The firewall is open for ports 7937, 7938 and 10000-10100; this port range is 
set on 'su001' with nsrports.

I'd appreciate any hint what may be wrong here. 


Thank you.
Thomas
