Authentication failed

Question

I getting the following message every time a group start the backup, but the rpcinfo can contact the clients and apparently the network configuration is ok because I can ping and the nslookup works:
Authentication failed or no valid authentication methods supported by both client and server, inside the daemon.raw

nw version 7.4.2
server, windows server 2003 r2..

Client and server are of the same version?This kind of error could happen when you have a server version 7.4.x and a client version 7.2.x or lower.

Same version - 7.4.2. The Windows version are also the same, 2003 R2.
The error only appear when the library mount the tape and, because the group didn't fail, he keeps trying to mount the tape. very strange

I've seen this only when server and storage node have different auth models set (nsrauth vs oldauth). Check it out.

NetWorker
