getting an error when you open EMC / EMS

  • Article

some times after you install service pack or update roll up for exchange 2010 you find that EMC / EMS are not working with below error

Connecting to 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.

 

looking at the application log we can see the below warning

looking at the above warning looks like something missed up in the web.config under power shell directory

 

if we edit the web.config we can see a variable called %ExchangeInstallDir% but that variable doesn't exist in the environment variable path, even after we add it still the issue is the same

so what i did here is replace this variable with the physical path as below

 

open web.config

Replace all "file:///%ExchangeInstallDir%" with "file:///D:\Program Files\Microsoft\Exchange Server\" where D is the drive where Exchange is installed

Save the file

iisreset

 

now EMC and EMS should open properly

    It worked, I must say I skeptical but now it leads me to think you could probably also reset the environment variable. Thanks
