Have been using Endpoint Manager 2017.3.3 for a few weeks now with no issues until today when we are now unable to work with 'Distribution Packages'. When we choose 'new -> windows -> exe' (or anything else) it returns "The remote server returned an error: (500) Internal Server Error", hitting ok clears the message and the executable properties window appears but if we then try to change the primary field option the same error then appears.
Likewise when trying to check the properties of an existing package this error appears.
Pasting the web path into browser results in this;
Have tried using the console directly on the server but get the same results. Looking about the community it would appear it is likely something to do with IIS permissions on the package share.
Within IIS the share details appear and can be accessed.
Being quite new to this any assistance would be appreciated.
