Seeing three errors:
(1) WARNING: Unable to locate a server document for this server - Hub1/Servers/Test/ESS
(2) Error reading server information for name server: The Domino Directory does not contain a server document for this server
(3) Connection denied: The server you connected to has a different name foom the one requested
-=-=-
Background:
*) Servers on their own private LAN, without any other Domino servers
*) Created new Certifier [/ESS] and OU Certifier [/Servers/Test] during installation
*) Red Hat AS 2.1 on xSeries (Intel)
*) First domino server in a new three-partition ND6.5.1 install TEST environment I created this weekend
*) Ran Remote ServerSetup on first server [Hub1]; remaining two servers yet to be setup
Current situation:
*) Java console works – no issues here
*) Admin client generates error (3)
*) Server console lists errors (1) & (2) [see below]
*) Host file contains the FQDN and alias for server as private IP rather than loopback (default)
*) Server document contains correct hostname on Basics tab and hostname alias [hub1] for Net Address on Notes Network Ports sub-tab
*) Server is correctly listed as Administration Server for Domino Directory
*) Server is Manager with full rights and roles for Domino Directory
*) Name stored within server.id equates name in sole server document with Domino Directory
*) ServerName= token in Notes.ini equates correctly spelled server name stored in server.id
*) ServerKeyFileName=server.id [and file exists in the current directory]
*) Server name as appears for Show Server and log entries contains only visible characters (as opposed to a prepended space, for example) " hub1" vs. “hub1” → {subtle error to track down}
*) Cleared out all three Server Document fields as listed in KB 167007 {$SavedAddresses ; $SavedPorts ; $SavedServers}
*) Verified that IP address is static (rather than DHCP); re-booted server for sanity purposes
*) Searched Google for newsgroup entries and followed advice [some suggestions included above]
*) Setup PortMapping within Hub1’s notes.ini file
*) “trace hub1/servers/test/ess” via server console works
Notation:
Initially, the IP Address was 192.168.1.118 during the server installation and setup process; realizing that the box was set to DHCP, I reset the IP to 192.168.1.3 as static and changed the host file and verified the server document entries; then bounced server to mitigate Domino cache issues.
Question:
a) Does Domino store the server’s IP somewhere that I missed? Using only hostnames in documents;
b) What’s causing these errors?
Would welcome any and all input. Thanks.
