Common Troubleshooting recommendations

If you exprience issues while configuring the MDT Web FrontEnd, please make sure you have a look on the following list of typical issues emerged so far:
  • Make sure you have the .Net Framework 3.5 SP1 installed. Be aware that it needs to be enabled as a “Feature” on Windows Server 2008 R2
  • Make sure you have IIS with ASP.Net Support configured
  • On IIS 6 you need to configure Wildcard mapping. See the Installation Guide for details.
  • Disable anonymous authentication and be sure to enable Windows authentication. It might be disabled on default installations of Windows Server 2008
  • Configure a specific account for the IIS application as described in the Documentation. On any problems add this account to the group of local administrators before any further troubleshooting. Permission problems constitute in weird error message not directly targeting to this. If the error does not occur after that you need to spent some time on getting the permissions right. I will add some general recommendations to the Installation Guide.
  • If you try to configure the Database connections via the Admin – Configuration tab it might take up to a minute to open this page. This should happen only if you have a Database server configured that can’t be reached at that moment. If it doesn’t show anything at all try to open the page http://localhost/YourFrontEndName/Admin/configure (while replacing YourFrontEndName :-) ). This should show you more information on the error happening. So far in most cases where this issue happened, it was due to disabled Windows authentication.

I am running Server 2012, SQL Server 2012 SP1, MDT 2012 Update 1, and SCCM 2012 SP1. I created your application within my webspace and get this error when trying to set authentication:
Filename: \\?\C:\Deployments\MDTWebFrontEnd\web.config
Line number: 14
Error: There is a duplicate 'System.web.extensions/scripting/scriptResourceHandler' section defined

I only see one of those sections defined in the web.config file. I cannot get past this error to continue the configuration

Thanks Maik, this is great!

One thing, I wanted to mention... I was getting this error:

"Could not load file or assembly 'microsoft.sqlserver.batchparser: An attempt was made to load a program with an incorrect format."

I had to go into the advanced settings of my application pool and set "enable 32-bit applications" to TRUE ( I was running 64-bit SQL Server).
