SSRS Authentication breaking Ajax
Before I get started it's important to note that this issue only happens in IIS7 and IE7, which means it works fine in all our IIS6 environments and Chrome and Firefox hitting IIS7.
We have an ASP.NET 3.5 application that is doing a very basic window.open to open our report server.
ex.
window.open('http://555.55.5.55/ReportServer', 'Reports');
Once launched the user is prompted for their username and password. If the user selects cancel and goes back to the parent window they can use all the Ajax functionality just fine; however, if the user logs into report server then all the Ajax functionality
on the parent window ceases to work (example error below). We changed the javascript line above to popup a window to google and everything worked fine. We even tried changing it to '_self' to act like a redirect and we had the same results, everything
failed. The issue appears to be related to something in IE7 and the authentication popup.
We've already set the application pool hosting the site in IIS7 to classic mode and this did not resolve our problem.
Error:
Error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by call to Reponse.Write(), response filters, HttpModules, or server
trace is enabled.
Details: Error Parsing near ' <!DOCTYPE html PUB'.
Any help would be greatly appreciated.

I found a solution to the problem.
Our website hosted in IIS7 is using port 80. This happened to be the same port SSRS. Once again IIS6 has no issues with these two using the same port; however, IIS7 is a different story and in order to fix the problem you must change the port
number SSRS uses in the Reporting Services Configuration Manager under "Web Service URL" from something other than 80.
