Hello,

Which tftp server you are using & which port on the NS5GT is connected to tftp server?

Also is tftp server directly connected to NS5GT?

Following error indicates that authentication-key on the NS 5GT is not able to authenticate ScreenOS version on the box.

Yeah initially i was using some small tftp server.

But read somewhere Solarwind TFTP server is better compared to others.

downloaded and tried that initially it was the same.Timeout.

Then i manually binded the ip to the tftp server.

Then it worked like a charm.

Now my NS5GT is working again.
