I hade a issue about this before and got an answer from the community that the problem was within some trend Micro drivers but now I got an answer from Trend Micro that it was not their fault that their Firewall driver gave a BSOD they say that they only used 500b. And the problem is within Vista 64bit, because the Microsoft drivers for (NETIO,tcpip,netbt) and stuff used almost all of the maximum 24K of stack space. Can this be correct? Is their a way to increase this stack space, if not is their a way to decrease the use of stackspace? The machine is a HP 8530p with a Intel(R) WiFi Link 5300 AGN networkcard I can upload a full memory dump -(a mini dump can be found in prev post) if that can be of any help to someone understanding this kinds of things previous post http://social.technet.microsoft.com/Forums/en-US/itprovistanetworking/thread/f488dafa-93cd-4127-a5eb-7df6e75fda2f/
