I am receiving an HTTP 500 Internal Server Error when using Transaction SOLMAN_SETUP from the Windows server 2012 server. The page is simply blank. I've also tried using Firefox. I can access the site http://<FQDN>:8000/sap/public/myssocntl?sap-client=001 from a remote computer as long as I call it from transaction SOLMAN_SETUP first. If I try to go directly to the site, it returns a blank page just like running locally on the server. It's almost like the SAP Logon's credentials are not being passed to the browser on Windows Server 2012. On the server, I can get to http://<FQDN>:8000/index.html.
I've checked the hosts file for the FQDN entry, as well as the icm/host_name_full parameter. They are good. I've tried replacing the FQDN:8000 with localhost:8000 and turned off Internet Explorer Enhanced Security.
I couldn't find any other discussions regarding this issue. Most of them had problems accessing the page remotely as well. I read somewhere that I need to access the page locally because remote logins are blocked to it remotely in order to log into the NWA_01 wizard for configuring a local SLD. I get a 403 Forbidden error when I try.
I'm guessing that this issue maybe unique to Windows Server 2012 and I'm hoping someone has come across a solution. Thank you!
