Unable to connect to server:RPC send operation failed


Hi All,

I am trying to add one of my SQL server to backup rotation. I have installed NW client software and SQL module but while adding the client from networker host getting below error

networker error1.PNG.png

Troubleshooting steps done from my side:

Ping -- working fine

nslookup -- working fine

rpcinfo -p  --working fine

ports : 7937 & 7938 are open

But when we run nsradmin command getting below

>nsradmin -p nsrexec

86948:nsradmin: Failed to initialize ports using nsrexecd on edvxedwsqlcp02a.redmond.corp.microsoft.com: RPC

Send operation failed; errno = An existing connection was forcibly closed by the remote host.

    Ok i forgot something. If you use NMM first thing we have to run NMM config checker ☺ It gives us detailed report on host. Did you run it before ? If no please run it and share the results.
