hi
i'm web developper at a big government foundation
i have abig problem at my job ..
i made a website developed by asp.net
this page is written in a good code development.

the case is :
i have dedicated web server and two isa servers(dmz area)
when i published the web page the page of .aspx is firing exeption(customerror)-runtime error-

but honestly on any local machine when i test this code at iis on it - i found it very good without any problem or any little bit of exception
