Error in Remote Web Access - "An unexpected error occurred. Please try again. If the problem continues, contact the person who manages your server."

Question

I have set up the RWA and I can log in to the web console with my server account. However when I click on any of the shared folders I get this error:
An unexpected error occurred.  Please try again.  If the problem continues, contact the person who manages your server.
Does anyone know how to troubleshoot this?
Regards,

I had this very same issue with one of our customer's servers that was running Windows Server Essentials. I ended up calling Microsoft about the issue. I hope this helps someone.

Troubleshooting Steps:
1.  We were getting unexpected errors while accessing shared folders remotely
2.  The tech found IIS handlers were missing
3.  She went to IIS > server level ( parent level) and added managed handler mapping  :
Name: svc-Integrated-4.0
Request path: *.svc
Executable: System.ServiceModel.Activation.ServiceHttpHandlerFactory, System.ServiceModel.Activation, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35
4. Added script mapping:
Name: svc-ISAPI-4.0_64bit
Request path: *.svc
Executable: windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll
Name: svc-ISAPI-4.0_32bit
Request path: *.svc
Executable: windir%\Microsoft.NET\Framework32\v4.0.30319\aspnet_isapi.dll
5. Ran IISreset.
6. We were able to access resources in Remote access, then.
