Hi,
this bugcheck is usually caused by drivers using improper addresses. Unfortunately no actual driver was mentioned but looking at your call stack it does look network related. I notice some of your drivers date from 2007 and if possible try updating to later versions.

Yeah looks like the BSOD is occurring in an IIS worker thread (w3wp.exe) and the actual BSOD is from the Windows networking subsystem NETIO. Since this is on a VMware box it could be the underlying network driver on the ESX host.
