I'd check few places:  OS server name, Net Address field in server's doc under Ports, hosts file (if used), and DNSServer= line.

My gut instinct says that Net Address and OS server name are not the same. Error comes up until server picks up DNS name.

hi,

1/ did you try to ping your remote server ? If yes, did it work ? if no, check your network settings on each hosts to be sure they can communicate together.

2/ If 1) is ok, On your Domino console, try to run Trace command ? You should see if your Domino servers can communicate togheter, and display how Domino servers try to join each others, IP addresses are displayed and if session can be opened successfully.

If you notice then IP addresses displayed after tracing command are different than into you operating system, Check if you have any wrong connection document into your public directory ?

SP.

Giedrius, you may be onto something.  Because this is a production server, and during Disaster Recovery testing we are restoring  the full domino server from tape, it could be that the OS name has the "wrong" Primary DNS suffix.

On the production server, it's in our WIndows domain, so it's DominoServer.AD_Domain.com

However, the original author of the operating system component of the script we use for Disaster Recovery has the correct computer name for the server, but has the Primary DNS suffix set to our company's Internet domain.

I'm going to make a note to change that setting during next years' test, and see if that error still occcur.

There is an entry in the hosts file on the recovered server that points to it's fully qualified internet host name (which is different than the server name) and it's correct IP.

And the DNSServer= line in the notes.ini is correct as well.

We also use AD. I never put FQDN in Domino server port configuration. I just use machine name without internet domain. So I have just DomServer instead of DomServer.AD.local. This way server has to resolve only the host it's running on without using DNS.

I've never had any issues by setting it this way. Hopefully it helps.
