For those having networking issues with ePrescribe and II opening, you can try the following using an elevated command prompt to change unnecessary settings on your network card:

Disable Receive-Side Scaling

netsh int tcp set global rss=disabled

Disable Task Offload

netsh int ip set global taskoffload=disabled

Disable Add-On Congestion Control Provider

netsch int ip set global congestion=none

Disable QoS

Go to NIC card properties -> Advanced -> Settings -> QoS (delete)
