This error:
The following error occurred when searching for On-Premises Exchange Server:
[server#.Domain] Connecting to the remote server failed with the following error message:
The WinRM client cannot process the request. It cannot determine the content type of the HTTP response from the destination computer. The content type is absent or invalid. For more information, see the about_Remote_Troubleshooting help topic
I've seen errors similar to this in these forums, but I haven't had any luck with the steps used to correct other's problems. The most recent steps I've taken are:
uninstalled and reinstalled IIS, then uninstalled and reinstalled CAS, along with various other fixes to no avail.
After installing Exchange and CAS the console was working for a couple of weeks, it died with this error after two things we can remember, although various other things may have been the cause:
1. installed a lengthy list of windows updates
2. installed the URL rewrite module: http://www.iis.net/expand/URLRewrite and set it up to rewrite http://domain to https://domain/owa, this has since been reverted and uninstalled, it still doesn't work.
