I want to download a CA or Lync certificate from my server, but when I try to access the site from the server, I get an HTTP Error 500.19 - Internal Server Error. The Requested page cannot be accessed because the related configuration data for the page is invalid. I will attach the screen of the error that I am getting.
The certificate is valid as I can still access e-mails via outlook web access.
Details of the server:
Is the Domain Controller and runs as a virtual machine
Windows 2012 Server Standard 64-bit
Xeon E5-2407 @ 2.20GHz
Please advise so that I can sort out this problem and be able to download certificates to be installed on new machines from time to time.
Please let me know if you require further information.
