I'm getting the following error while setting up the site in Windows server 2008. This site was running fine in IIS 6 (.Net 3.5) and I tried to migrate to Windows 2008/IIS 7 and Net 4.0. I'm not sure if I'm missing any setting(s). Kindly help
I getting this error from global.asax
[NullReferenceException: Object reference not set to an instance of an object.] System.Web.Security.UrlAuthorizationModule.CheckUrlAccessForPrincipal(String virtualPath, IPrincipal user, String verb) +791

Thanks in advance,
There are quite a lot of differences in configs between IIS6 and IIS7 so they generally don't work just by moving from one environment to another. .NET4 is an extra complication even though it is generally smaller. I suggest you roll back to .NET 3.5 and then look at these articles and others to try to get your config to work:
http://world.episerver.com/Documentation/Items/Tech-Notes/EPiServer-CMS-5/EPiServer-CMS-5-R2-SP1/Changes-Between-IIS6-and-IIS7/ (never mind it is for CMS 5 R2, the basic differences between IIS 6 and 7 remain)
http://www.markeverard.com/blog/2010/05/21/default-episerver-web-configs-for-iis6-and-iis7/ (for default configs)
Generally it is good advice to install a default site in your target environment (IIS7) and then use the configs from the default site as a template to which you add the things that are specific to your site.
Hi Magnus,Thanks a lot for the suggestion. The idea of installing the default site and the links helped to find the differences.
