We install ColdFusion 2016 on Window 2012 server with IIS 8.5. It works fine for couple days, then the admin screen login in screen return blank white page.
After play with security and IIS setting, we re-installed ColdFusion and it comes back. After a week, it happens again. What could cause that ?
It looks like you are already in touch with one of our team members for this issue. We will look into this issue.

As we discussed over phone, ColdFusion administrator needs to be accessed from internal port 8500 from CF 2016 onwards.
So, with CF2016 there is no way to set up IIS to handle the access to the CF Administrator? Is there some kind of block that says, "only Tomcat can serve these things?"
I thought that was only if the CF server was using the built-in webserver? The OP is apparently using IIS 8.5. Or did they change it in CF2016?
I have WS 2012 R2, IIS 8.5...when accessing administrator via virtual directory in IIS I see an empty white page. When accessing via the built-in web server I am able to fully administer. It's as if there is code that says, if this isn't tomcat...show 'em nothing!
That's a little confusing. If you have the built-in webserver serving the pages, then you should not be able to access it from IIS. If you have the wsconfig set for IIS, then you should not be able to access CFAdmin via the built-in webserver.
Which did you select during the wsconfig?
wsconfig: IIS points to the particular CF server. I'm not sure how that's relevant to what the built in web server is doing.
IIS > Instance via wsconfig
built in web server - not really even sure how it's set up to connect to a particular instance, although I'm guessing in server.xml (i.e. doesn't use wsconfig)
