Hi Sebastian

Thanks for your reply. Actually I have tried parent portals, but it did not work. Can you help me?  Here is my query.

I have windows XP and developing application using localhost(I.P. address 192.168.169.8). I have installed DotNetNuke in the folder F:\dotnetnuke. Then I have created a virtual directory dnn and mapped it to that folder.
For  my default website, I have two Portal Aliases - i) localhost/dnn (default) ii)192.168.169.8/dnn ( I have added, so that I can see my page from other machine).

Firstly I have tried child portals. I have added a new portal
192.168.169.8/dnn/lake. Here a site is created with default menu. Its portal id is assigned  1. I can add new page.  For this child portal, a new folder lake and default.aspx is created.

Secondly I have tried parent portals. I have added a new portal  192.168.169.8/city. Here also a portal id (2) is created.  But no site(i.e with home, admin menu )  is created. It creates a blank page(i.e. The page cannot be found. ....  ). For this site no folder and default.aspx is created. Even I cannot enter into the page entering the userid and password , which I have made during partent portal creation. How will I add pages for this parent portal ?

Thanks a lot. I was looking for this answer. I will not try anymore in localhost.
I have another browser problem. My  website has two more menu beside Home.  I am using localhost.   In my machine I can see all the three menus, both  in IE and Firefox.   To see the page I am entering http://192.168.169.8/dnn.  Now when I am seeing that site from other machine in IE, I can see all the menus. No problem. But when I am trying to see that site from  other machine( Windows or Linux)  in Firefox, I can see only the Home menu. I am using the default skin. I am having no problem to see www.dotnetnuke.com ( i.e. with all menu/submenu)  in Firefox in anytype of machine(Windows or Linux).
Why I cannot see other menus in Firefox from other machine? What I have done wrong?
