TCP retransmissions typically occur because of network congestion. When troubleshooting, pay attention to the presence of a significant number of broadcast packets at the time the issue arises. If the proportion of broadcast traffic in your capture exceeds approximately 3% of the total captured traffic, it indicates congestion. Be sure to examine both physical layer broadcasts (ARP) and network layer broadcasts (name resolution) on the network

Hi,

Thanks for good idea- Is there any way to modify/increase the threshold for a specific IIS process?

You should do it at host-level
