I am having a problem with setting up WebDav.  It seems to be working with the exception of the step to add a “Wildcard application map” for the “c:\windows\microsoft.net\framework\v2.0.50727\aspnet_isapi.dll” file.  I have verified the file path.  When I add that, I get the error indented below.  There weren't any errors on installation and the module and WebDav seem to be working.  I am, however, having issues using WebDav in Internet Explorer 7.  In Internet Explorer 6 it seems to working just fine, but IE7 will be prompted for authentication like others have mentioned, where it won't accept any credentials.  I don’t know if the two problems are related, but any help would be appreciated.

My web server is: Windows 2003 SP2 / IIS 6 / DNN 4.07 / DMX 4.02 / SQL Express 2005.  I have fresh installed the website twice now with the same result.

Server Error in '/' Application.

I read my first post again and I want to clearify that the issue with the Wildcard Application map is seperate from the issue with IE7.  If I add that dll to the wildcard application map the site will no longer load.  If I remove it the site appears to work, at least with IE6.  In IE7 the experience is inconsistant.  It seems that I can get into the webdav and navigate the folder structure after cancelling the authentication challenge, but I am unable to modify anything.
