Unable to create lan game, issue related to having hyper-v enabled virtual switch

Hi All,

I would like to report an issue I encoutered with CnCnet client. Whenever I try to host a game by clicking lan game and then clicking create game, I get an instant crash with the following messages:

Yuri's Revenge has crashed. Error message:

"An attempt was made to access a socket in a way forbidden by its access permissions"

"No connection could be made because the target machine actively refused it 127.0.0.1:1233"

I have figured that this only happens on a machine with Hyper-V enabled, and I suspect it might be due to the virtual switch. So let's say I need to have the virtual switch still on, is there a quick fix for this? I do not understand networking sufficiently to fix this.
 

Extracted from my client.log

Found the solution from here:

https://stackoverflow.com/questions/15619921/an-attempt-was-made-to-access-a-socket-in-a-way-forbidden-by-its-access-permissi

Just change 3001 to 1233

 

Disable Hyper-V:

dism.exe /Online /Disable-Feature:Microsoft-Hyper-V


After the required restarts, reserve the port you want so Hyper-V doesn't reserve it back:

netsh int ipv4 add excludedportrange protocol=tcp startport=1233 numberofports=1


Reenable Hyper-V:

dism.exe /Online /Enable-Feature:Microsoft-Hyper-V /All
