iPXE ifconf fails with error 0x20c613c

Applies to
iPXE Anywhere 2PXE Server

Symptoms
iPXE Anywhere boot splash screen indicates an error:

The ifconf failed with error 0x20c613c

Cause
Following the link provided ( http://ipxe.org/err/020c61 ) you will note that Error 0x20c613c indicates a HTTP error 401.

When using  HTTP the DP would not be set to "Allow anonymous access".

Solution
In this scenario, to allow access to network resources  you must configure 2PXE to use a low privilege account (same as the Network Access Account for example) in the 2Pint.2PXE.Service.exe.config file:-

  <add key="Username" value="DOMAIN\UserAccount"/>

and also enter the password in the password.config file and restart the service. The password is encrypted using machine encryption and is not readable after service startup.
