Hi Rob I started the admin server today to generate error logs and the error seems to have disappeared. I think it might have to do with the server having multiple dns entries pointing to it''s single ip address ?!? Thanks for you help.

Thereafter I ran into the imb jdk hyper threading issue when trying to start the admin server and thus replaced the jdk with sun jdk 1.4.2_08. This resolved my problem of starting the admin server, but when I try to access the admin server running on port 9000, I receive the following error: Internal Error The administration server was unable to fulfill your request. Reason: uri2path: Invalid URL! Is there anything interesting in the error log (server-root/admin-serv/logs/error) What URI of the admin server are you attempting to access? rob
