Hi,

If you are using NT32 platform, please check whether you already have 
SnpNt32Io.dll, since NT32 platform uses SnpNt32Dxe module to produce SNP 
protocol, and this module depends on the WinPcap to transmit and receive 
packets on Windows systems. If you don’t have, please get one from 
https://github.com/tianocore/tianocore.github.io/wiki/Network-io.



Best Regards,

Ye Ting

Subject: [edk2] Not able to locate EFI_TCP4_PROTOCOL protocol

Hi,

I am trying to write a TCP application. I am seeing 
bootservices->LocateProtocol() for EFI_TCP4_PROTOCOL failing. Although TCP4DXE 
driver is loaded as per drivers command. But when I load this TCP4DXE driver 
manually I don't see EFI_TCP4_PROTOCOL handle is getting installed. I am 
testing all this on NT32.

Just wanted to know which driver to load so that I can locate 
EFI_TCP4_PROTOCOL? I want to open a TCP socket so that I can communicate with a 
remote host.

Thanks.
