No Route Found To Server Problems --Details here

Hi everyone: Router between my server still not works now. So, I put details about my server here ,and ask for some sugguestions.

a.Server Documents, each server have host name in server document, and ping host name to each other is works well.

b. which configuration document I need to set? I have no configuration document now.

c.Both servers are in same domain.

d.Also ,I have connection documents to each other.

e.Both servers are sending message through NRPC.

I have already tried these things:

a.use trace in server console ,it works well.

b.install two servers with original names.nsf and id, still not work.

c.Already compacted ,fixed and updated names.nsf.

Thanks for any help.
