Report Manager URL displays blank page in IE

Having installed and configured Reporting Services on a new laptop, I found that on entering the report server URL in IE (running as administrator), IE repeatedly popped up a dialogue asking for the password (3 times), then finally displayed a blank page.

To solve this I had to do the following extra configuration steps, in addition to the usual recommendations:

1. Ensure that the Windows account of the current logon meets the security policy configured for RS (in my case it did not have a password which was causing a problem).
2. Add the Report Manager website to the Local Intranets zone in IE.
