lotus notes replication

Dear Xman San,

The first step in solveing the problem would be to give us much more information. We can't see what you see on your screen, so you have to help us help you.

Several questions:
- how do you know that replication doesn't work? what error messages do you get (e.g. in the log.nsf database)? can you post them?
- did it work yesterday, or before that? if so, what happened?
- can you PING server A from server B and the other way round?
- can you connect to both servers, using a Notes client?

There may be more questions when you added your answers.

Post results from doing trace {servername} from console that will often highlight any network issue.

I will try it.
Any more useful notes command can help me to check replication?

1 We have two hub notes Servers. They are in cluster.
When one of them shutdown, I found that two connection error
come out from Console. One is the shutdown error from shutdown Server.
One is unknown Server.  Therefore, I want to find where is the
information of unknown error sitting.

2 After consult to my colleagues, the unknown Server is exist.

3 Therefore, I want to solve the problem. How?

We still can't see what you see on your screen, so you have to help us help you. But you don't give us much more information. Please provide answers to our questions above (logs, traces, etc.)

Where can I find the log?

In the log.nsf database on the server, the Miscellaneous section...

Would you give me full location of finding log ?

After further testing, we found that when hub1 shutdown,the hub2 operating and
we can send notes mail or email but we cannot receive
any notes mail or email.
Moreover, the other location cannot telnet the hub2 server.

File/Application/Open, select your server and in the filename field type log.nsf

I will check.it.

Thanks for your advice!
 I check with our networking and correct the router setting,
we found that. we can send and receive the notes mail when main Domino shut down.

However, we found that we can send email via secondary Domino Server but we cannot receive any email.

Please help!

Any update ?

> ... we cannot receive any email.
Meaning: mail doesn't arrive on the Domino server, mail isn't added to the user's mail database or the mail database cannot be opened in the Notes client?

Did you check the log.nsf database on the server(s)?

incoming and outgoing suddenly ok,after correct network router.
