Lightswitch IIS 7.5 Deployment - GetAuthenticationInfo

Question

I am having an absolute nightmare with the "Load operation failed for query 'GetAuthenticationInfo'. [HttpWebRequest_WebException_RemoteServer]" error when deploying my applications to a new server.

The apps I have are working and have been running for a while on another server. I have now got to move them to a new one, and I cannot get anything to work!

I have been through all of the posts on this error and have tried almost everything to get this deployment working.

Old Server: Win 2008 R2

New Server: Win 2008 R2

At first I thought it had something to do with Devexpress Xtra reports but I have disproved that by creating a bare bones app with one screen and one table and no extentions. And it still fails. I have also tried this with every combination of authentication. I have also deployed this test app to the old server and it all works fine, so I am sure there must be something wrong with my IIS settings. Visual studio is publishing the app with no errors. I only get it on runtime. I have tried to use fiddler to get a clue as to what is going on but I cant find anything useful.

I have also tried:

• removing and adding the web server role on the new server to try and reset configurations.

• Deploying several known working LS applications

• Every combination of Authentication on the IIS server for the app, website and server level

• Tried syncing the IIS configuration with the old server using MSdeploy.exe cmd line

• Repairing the .NET Framework 4 Client prile & extended

• restarting the server

• Installing updates

• re installing web deploy

• Made sure the application pool was .net v4

• made sure the application pool was integrated

• changed the authentication on app pool user to a domain account with known admin rights to the server (and have now put back to apppool identity)

• Creating a new website and deploying the app into there

• restarting web services

• Installing Lightswitch 2012 Server pre-requisites

None of these have worked at all.

The only way I can get my deployed application to load into a screen is to buid as a web type and change the url from

http://server/otm

to

http://server/otm/default.htm?IsLaunchedByVS=True&AuthenticationType=None

Something which I think it could be related to is a faulty installation of "Lightswitch Server Configuration" which installed using the Web Platform Installer 4.5 This however is not showing in the Add/Remove programs list, so I cannot uninstall it to see if it is messing things up. I cant seem to uninstall it from the WPI and i also cant find a direct download link from Microsoft.

I am completley out of ideas and in big trouble as these are production applications and the old serve will be shut down within the next two weeks. Any help would be appreciated!
