Because in windows how to set the retransmission and ack timeout?

Hello,

 

Thank you for posting in Q&A forum.

To modify the retransmission limit, please kindly follow below steps:

1.Run "Win + R", input regedit and hit Enter to open the registry editor

2.Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters.

3.Modify the value of InitialRttData as 10. (10000=1 second)

4.Restart the system and check if it works.
