The page cannot be found in Infoview

In Business Objects XI, you may get an error saying The page cannot be found when trying to access InfoView or the Central Management Console. One cause for this problem is that, on Windows Server 2003, IIS 6.0 blocks .NET 2.o .aspx applications by default. To enable them, go to Administrative Tools -> Internet Information Services (IIS) Manager, click the Web Service Extensions, select ASP .NET v2.0xxxx and click Allow.
