Unable to open the thick Client in local System?

This is a common error which is faced by those who are new to Siebel.
This can be fixed by making few parameters change in the CFG file under BIN folder.
There are 2 parameters...

Initial Value of these parameters are ..
RemoteSearchServerPath   = $(FulcrumHost)/tcp$(FulcrumPort)
EnableFQDN               = True

Please change these parameter vlaues to
RemoteSearchServerPath   = localhost
EnableFQDN               = false

Please modify these values and restart your local client!
