Error Installing DottNuke under Windows Server 2008/IIS 7.0

My DotNetNuke installation o Wondows Server 2008/IIS 7.0 was affected by the recent upgrade to .Net 4. I was instructed to reset my .Net level to 4.0. So my .Net Framework has now been set to 4.0 and I reinstalled DotNetNuke. I did receive an error message about duplicate entries and I then checked the info at a link provided (http://forums.asp.net/p/1571308/3939106.aspx) in response to my support ticket asking how to get my DotNetNuke installation to work again.
As suggested in the link article, I commented out/removed all references to "system.web.extensions" in the web.config file. I am now getting an error of "Object reference not set to an instance of an object." I do not know what to do to resolve this error.
This brings me to a question as to why DiscountAsp provides DotNetNuke as an installable app via the web app gallery and yet it cannot be installed without an error under Windows Server 2008/IIS 7.0. This latest error appears to be due the upgrade to .Net 4.0. I had previously successfully installed DotNetuke and then the upgrade to .Net 4.0 led to it no longer running correctly without a "fix" to the web.config file.
It would seem to me that DiscountAsp needs to provide the proper web.config file so that DotNetuke can be installed without errors. This is not an issue of me doing a custom install such that it's my fault DotNetNuke is not installing correctly. Seems like I should either be able to do a straightforward successful install of DotNetNuke via the Web App Gallery or DiscountAsp should not offer DotNetNuke at all.
In the meantime, I'm needing a clean web.config file with the DotNetNuke app so I can successfully install it under Windows Server 2008/IIS 7.0 Seems like DiscountAsp should be able to acquire that as part of the complete install package for DotNetNuke running under Windows Server 2008/IIS 7.0.
Thanks, David

 

Hi David,
did you get DNN working?

To anyone else who might have DNN 6.1.3. installed here at discount asp and might know the answer.

I migrated my DNN 3.3.7 from an old DASP server a new 2008 server, dot net 4.0 and IIS7 and set the pipelining to classic and it worked fine. Perfect.

I then deleted all code and loaded up my DNN 6.1.3. that has been working on my 2008 R2 x64 with sql server 2008r2 and I get this thrown back at me.

http://www.instantbi.com/Default.aspx?tabid=36&error=An unexpected error has occurred&content=0

I am thinking that I need to connect to the IIS server and set permissions of the folder or something like that.

I am in IIS7 manager on my 2008 R2 machine and have connect to a server in front of me but when it throws up the server name I am at a bit of a loss as to how to get over to the ASP server.

All ideas most welcome.

Thanks

Peter

PS. I go into IIS Manager and I put

instanbico.web713.discountasp.net as the server to connect to.

I then put the userid instantbico which has been authorised for IIS and I put the password in for this account....I get not authorised back.

All ideas welcome.
