Unexpected Response from webservice . 404 not found.

Hi All,

I recently downloaded the the PGFE files. I followed the instructions on how to install it.


I can't get the PGFE to display. The correct boot image is downloaded but when WinPE loads I get what looks like a flicker of a command window and the computer will eventually reboot.


The BDD.log file lists 'unexpected response from the web service. 404 not found'.


As well as 'unexpected response from the web service. 500 Internal server error'. System.SecurityException: request for permission of type 'System.Web.AspNetHostingPermission, System, Version =


Thanks for your help.

Hi Mick!

A late answer, but maybe it'll help someone else. I had the same problem. Check which Application Pool 'WsFrontEnd' uses from Basic Settings for the application in the IIS. Then select Advanced Settings for that Application Pool and see what Identity that Application Pool is using. I switched to Local System and everything worked after that.
