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
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.

Is your ipv6enabled on client side ? If yes can you try disabling it and then retry

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.

Yes it is possible but you are trying to use NMM for sql backups. As i remember as IPV6 is not recommended yet.
