On a 2008 sp2 64 bit with 12 gig of ram. This servers primary role is a file and print server and does not have any applications installed. Today I experainced 3 sequential BSOD from the first dump occured 4 minutes later another dump and then 14 minutes after the 2nd dump it BSOD again. It has now been running for 2 hours now with out issue. From experiance this will continue so I examined the memory.dmp file that was produced and it is leading towards the netio.sys. I attached the information from windbg. Unfortunatley there is not a lot of information available as to what the cause could be. This server at one time had network driver with a memory leak. We downloaded and instlalled the latest driver and that solved that problem but that was over a month and a half ago, so I dont think that is related. Other than that nothing has been installed or changed. Any insight that can be provided would be helpful.
