Hi Mangesh,
during installation you should have been asked to provide a password for user Administrator.
Try to login to MWS with Administrator and this password.
If this does not work login with SysAdmin and navigate to Administration Dashboard → User Management → Users and check user Administrator.
Check the check box to enable it for the case it might be disabled for login and provide a new password if neccessary.
After that you can login with Administrator and the new password.
When adding custom users, which should be able to use the administrative pages, add them to the “My webMethods Administrators” Role or the SysAdmin Role.
Additionally you might need to adjust the evaluation order of the Rules (Skin, Shell and Startpage) to get proper layout.
Regards,
Holger
