I don't see it asked in any of the previous posts but you don't mention your authentication method. If you are using LDAP/AD integration that error could be caused by several things. One is a bug in Networker 8.0.2 that we discovered and two you could be trying to connect to Networker using a 7.x Console Server to  a Networker Server running 8.x, such a combination doesn't support LDAP/AD integrated authentication.

Is 8.0.2 bug fixed now?

You need delete records (servename) from Clients/Groups & Local Host;

If issue still exists, delete peer information:

only on the server:

On the networker server:

nsradmin -p nsrexec

print type: nsr peer information; name:   name and domaine like this "server.domain.com"

delete

if you tape only the name of the client not the fqdn this procedure do not work
