Hmm, I dont think so cause it was working fine till the end of last week. Its a windows client.

Do you have something as wake-up-on-LAN there?  I have seen this with some Solaris boxes and older NIC drivers.  It would go into sleep and you would need to wake up interface and then connection would work again.

Hi there,

Have you checked the ports? Are port 7937 to 9936 opened?

What is the output of the following commands?:

On NW server:

rpcinfo -p client_name

On Client:

rpcinfo -p NW_SERVER

Also try to run nsradmin -s xxxx -p nsrexecd on server to client and on client to server.

Thank you,

Carlos

Forgot...redirect the output to a file for further analysis.

Thank you,

Carlos

Hi Carlos,

The ports are open from 7937 to 9936. Here are the outputs. Infact, the backup works as soon as I run it after doing 'nsradmin -s client -p nsrexecd' from backup server.

Outout of nsrports -s client:

Service ports: 7937-9936

Connection ports: 0-0

from NW server: rpcinfo -p client

Hi,

Have you tried a manual backup from client?:

save -D3vvv -s NW_SERVER -b pool -N "SAVESET"

where SAVESET would be for example "C:\tmp" for Windows or "/etc/hosts" for Unix.

Thank you,

Carlos
