you can find out the hostname for the box by going to it and opening a browser window and typing in
(or 9496). The LCF daemon page should display. The page will contain both the endpoint label and the endpoint version.
Have you patched, upgraded or possibly renamed your TMR server? There are two issues similar to yours in the Tivoli support database that involve the same error message.
Problem
" TNR_errors:0003
An instance named "EnterpriseClient" of resource "Presentation" was not found.
+ [ 1 -ne 0 ]
+ set -e
1"
This message occurs when "wlookup -r Presentation EnterpriseClient" is issued, and Tivoli Enterprise Console (TEC) and ACF will not install after upgrading Framework.
Solution
Always reexec all oservs after applying Framework Patch.

Problem
"Error::TNR_errors:0003 An instance named "oldserver" of resource "ManagedNode" was not found." error occurs and rules will not compile after the server is renamed.
Solution
CAUSE: "Error::TNR_errors:0003 An instance named "oldserver" of resource "ManagedNode" was not found." error occurs because the old server name exists in the rulebase path in the properties for the rulebase.
SOLUTION: Link the "old server name" "new server name" directories together so the contents of both are the same.
