Remote system error - Network is unreachable

If you google you will find a lot of entries for that error message. Unfortunately, the NW Error Message Guide does not have any hint. I expect trouble with the firewall ports (9737 & 9738)

You better start with a communication check between the clients as this is mandatory for the communication. The standard procedure is to run

  nsradmin -p nsrexec -s name

from both sides. So you should use

  from the NW server     nsradmin -p nsrexec -s client_name        and

  from the NW client      nsradmin -p nsrexec -s server_name        to verify a positive connection.

Also let us know your NW versions. Using savefs tells me that you use a pretty old environment.

Hi 

 Do we need to check firewall port  9737 and 9738 ???  or 7937 and 7938??

" I expect trouble with the firewall ports (9737 & 9738) "

from the NW server     nsradmin -p nsrexec -s client_name        and

  from the NW client      nsradmin -p nsrexec -s server_name        is working deom both client and server end/

networker version is  19.3 

Please let us know any solution

Sorry, my fault. Of course the ports did not change at all over all years.

Besides that your problem is not easy to investigate. First of all I would check whether this is a new client or whether it has already worked in the past.

If it is an older installation then something within the network must have changed that NW now fails.

If it is a new configuration, you might download the NetWorker Test & Troubleshooting Tool NTT from the NetWorker site. Install and run it - it will give you much more details.

Hi Experts,

We removed and again added the client name in the host file of the backup server with the proper FQDN 

so we are bale to take backup now.

the issue was resolved .

thank you for the advice/tips
