If you get the following error when trying to export a Local Reporting services report to excel or pdf:
Internet Explorer cannot download … ReportViewerWebControl.axd from <server name>
Internet explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later.
You might want to check the properties on your virtual directory. Here is mine before I made the change. As you can see it is set to “no-cache”. What I think is happening is that IE downloads the excel/pdf file (confirmed this via fiddler) then deletes it, then tries to open it.
To fix the issue I removed the three lines in the middle:
Cache-Control: no-cache
Pragma: no-cache
Expires: 0
Hope this helps you out. . . .
