This applies to both USS Gateway and USS Agent


If you are experiencing unexpected behaviour with the USS Agent or USS Gateway, it may be that a proxy configuration exists for the Windows system user account. This can be left behind by third party anti-malware software or deployments of old proxy products.


To determine if a proxy is configured for the system user:


1. Download the pstools application from Microsoft


2. Extract the archive, then up a command prompt as administrator


3. Run the following command: 


psexec -s -i "c:\Program Files (x86)\Internet Explorer\iexplore.exe"


This will open up Internet Explorer whilst running as the local system user


4. Go to Tools -> Internet Options -> Connections -> LAN Settings


5. Remove or disable any configured proxy settings


6. Reboot
