When running several AdminUI's, there is no tool such as 'smreghost' to re-register a given AdminUI.
This process needs to be done manually and the following indicates how to re-register only 1 AdminUI when there are several set for the same environment.

2. If the AdminUI runs on Linux, insure that /dev/random is linked
to /dev/urandom or insure that rngd daemon is running;
