Object reference not set to an instance of an object 

hi all,

just started using DNN, great app.

i can't seem to "publish" my site to IIS without the following errors. if i run it within VS2005pro, it executes successfully, but for the love of me, can't figure out why it keeps displaying the following messages. ( the 2nd message is when i hit F5 again). I've even gone to the extent to give full perms to the c:\inetpub\wwwroot\dotnetnuke directory. (aspnet user, everyone, etc)

OS: W2KPro, Visual Studio Pro 2005, IIS 6

this is my dev system:

thanks, any help appreciated.

Johnny

Re: Object reference not set to an instance of an object 
Did you add the hostname of your iis site to the list of http aliases of your default portal?

Cheers,

Erik

Re: Object reference not set to an instance of an object 

Hey there!

I'm new to DNN too and I have the same problem.

Where can I add the hostname of my iis site to http aliases? I can't find where I can do that.

Thank you all, Jože

Re: Object reference not set to an instance of an object 

you have to log on as host, then go to admin > site settings. At the bottom of that page you can add http aliases to the portal

If your site is not working, but if you have access to the db, you can add a new record to the PortalAlias table. Make sure you use the correct PortalID (0 for the first portal). If you follow this route, you have to recycle the IIS process, because dnn caches the list of portal aliases....

cheers,

erik
