Hello Experts,
I am having a problem after creating a child portal.

I created a child portal successfully. But, incase when I receive any error on Child Portal (application crash on child portal OR anything like for say; object reference error) - and after error when I click on any menu, link, logo - the url always redirect to parent portal... Is there any setting anywhere that if any error occured then still all the links and menu redirect user to child portal itself..

whole scenario is below:
Ώ] parent portal - http://localhost/abc
ΐ] while i click on any child portal - url becomes - http://localhost/abc/Default.aspx?alias=localhost/abc/xyz
Α] incase if any error occured while going thru pages in child portal; url becomes - http://localhost/abc/xyz/pqr.aspx
Β] when i click on any link, logo or any menu option it redirects to parent portal - http://localhost/abc

even on a fresh install i found this problem..

i checked that Default.aspx is set as default document.

TIA

 i am using 5.1
