Hi all,
I am getting an error message on web page(Production) like as below.
Msg: Invalid access permission. You are not authorized to view this page. 
But we have permission to view this page. But dont why its showing. When i debugged this its showing error.aspx page and returning above message. How can i solve this. PLz help me.
Sol: 
We have debugged this, and feel that it is due to the machine keys not being the same on all the four boxes(load balanced servers). The keys are the same on 218 and 221, and are the same on 219 and 220. Therefore when the user is sometimes led to crossover from one set to another, his aspxauth cookie which is encrypted using the machine key is not recognized and therefore the application throws an invalid permission error.
Above solution i cant able to understand. How can i check machine keys in four boxes whether its same or not.
Plz help me. ...

Go to the complete details ...
