Resolution:
Issue the LIST REPOSITORY command in Batch Registry.

The directory listed should match the location of the repository,
and the repository id should match the contents of the reposit.id file
in that directory.  If reposit.id doesn't match the id, the reposit.id
file can be edited by hand to match the id.

DO NOT update the repository_id in the database!

The error can also happen if the RepDeamon is not running or USER-ID does not match the owner of the repository directory.  In the latter case
commenting out the USER-ID in the IC_HOME/config/IcRepDaemon.config file fixes the problem once the RepDaemon is restarted.

Lastly the error message will happen if the port of the IcRepDaemon is being blocked.  The following test covers that issue:
I want you to perform the following test from the machine you are running the PC GUI on:

================================
from PC_GUI_machine:
telnet &ltwf_machine> 7170
Trying...
Connected to stbwf01s.
Escape character is '^]'.

================================

A CR will break the session and then you will see connecton closed by host.  This is positive test and it means 7170 port (repo server port) is working and reachable from BW machine (client).  If you get connection refused then the Repository Deamon is not reachable.
