Anyone running AC with Windows Server 2016/IIS 10?

I am trying to test it out, but running into the following error when the site attempts to load:

Code: Select all

Server Error in '/' Application.

I usually see that error when the site can't connect to the database.

I have verified that the I can connect to the database from the server.

Was wondering if there is something different about IIS 10 that maybe needs to set/changed?

Hello, AC Gold 12R2 is working fine here on Server 2016. Didn't have to tweak anything in IIS.

Eldon I assume (by now) that you got this fixed?

I've seen that message happen when there is a duplication between the site specific web.config file and the server-wide file applicationhost.config. There are actually two web.config files on an IIS server. One is called applicationhost.config and applies to all websites hosted by that server's IIS process. The second is the web.config specific to each individual website.

On rare occasions, there will be something specified in the applicationhost.config file that is ALSO specified in the individual site's web.config file. When this happens, it can confuse Able as it tries to parse for certain configuration values.

And as Judy said, I've too have seen it happen where there's an issue with the .Net application trying to connect/access the SQL database. I usually test SQL connections from the web server by creating a test connection in Control Panel/ODBC connections section.
