Customers that have bad network connectivity between the PXE/Site server and the Notification server may see PXE drop the connection to the DS web service.
PXE will not return a menu to computers in automation due to poor network connectivity.
All of DS up to and including 8.0 HF2.
The PXE server did not have a robust way to deal with poor network connectivity when querying the DS web service to gather details about clients.
This issue has been fixed for HTTP PXE connections in 8.0 HF3.
NOTE: If customers experience similar issues with PXE when it is using HTTPS protocol, please notify support.
