Thank guys!!! We did this problem!

I did this:

Run the following commands on both NetWorker Server and the problematic client:

C:\>nsradmin -p nsrexec
NetWorker administration program.
Use the "help" command for help.
nsradmin> . type: nsrla
Current query set
nsradmin> show auth methods
nsradmin> print

Does it show as below on both NetWorker Server and the problematic client?

auth methods: "0.0.0.0/0,nsrauth/oldauth"; 

If not, run:

update auth methods:"0.0.0.0/0, nsrauth/oldauth "

2. Update peer information:

On the client:

nsradmin -p nsrexec
print type: nsr peer information; name: <networker server name>
delete

On the networker server:

nsradmin -p nsrexec
print type: nsr peer information; name: <client name>
delete


My problem disappeared!!!

Do you have any error message in daemon.raw?  Something about peer information?  That could be one reason not to have this working (or nsrauth disabled).  You can try to defined it manually without wizard use and that should work just fine.

Authentication errors can occur for multiple reasons and  may be indicative of   multiple issues that need to be addressed. In order to  provide the most accurate fix, review each of the following  resolutions as one or more may apply to the environment:

  1. On the client machine, ensure that nsrexecd process is available.   
  2. Update the client's /nsr/res/servers (UNIX) or C:\Program Files\Legato\nsr\res\servers (Windows) file with all known aliases for the NetWorker server.   
  3. Verify that name resolution between backup server and client is working correctly.  This includes all NIC's on the NetWorker client are resolvable by the backup server (Include reverse name lookup).

If the issue persists, disablethe use of GSS strong auth from NMC or using nsradmin.

nsradmin -p nsrexec

. type:NSRLA

show auth methods

print

update auth methods= "0.0.0.0/0,oldauth”

y

print

I assume you are still referring to the same Host X as Host Y !!

On Both the server and the respective client machine make a host entry for one another. i.e on the Client machine make a hosts entry for the server IP/hostname and on the server make a hosts entry for the client machine's IP/Hostname.

Have you tried renaming the /nsr/res/nsrladb and /nsr/tmp on the client machine to get rid of any corrupt or unwanted entries? If not please give that a try too.

Also, does your NetWorker server have more than one IP address ? If yes, define all the IP's in the client machines Hosts file too.

On the NW server, run "nsradmin -p nsrexec -s <nw_client>".

  - If the client does respond the connection itself is fine. However the client may still reject the request due to a wrong permission.

    In this case - on the NW client:

       - Stop the NW client daemon

       - Add/correct the NW server to ../nsr/res/servers

       - restart the NW client daemon to reread the file

  - However, if the client does not respond, it is most likely that the ports have not been opened (7937 & 7938)
