How to Open UDDI Registry

Hi All,
I am new to 7.1 webservice,Please can any one explain how to open UDDI Registry in my local system and what is the meaning of inquiry,security,public,username,password.

-how to define these fields.
please can you specify any post or documents about this problem.

If you have already installed CentraSite then you need to pass the hostname of that machine along with the port number (http://localhost:53307/UddiRegistry/security).
Submit the valid credentials of this instance and set up the connection between IS and UDDI Registry.
I hope this helps you to sort out the issue.
