Hi, I'm a helpdesk guy at a credit union. Recently our CEO's computer had a BSOD. After restarting we kept seeing the error: "(program) failed to start. This program failed to start because netrvn.dll could not be found. ....." Multiple programs would not run, and there are too many problems to run the OS. I've replaced his computer and I am just highly curious.... WHAT IS NETRVN.DLL??? Google shows no results, its one of my biggest tools.. and if google didnt find it, then it doesnt exsist. If it doesnt exsist, why are these programs (such as lsass.exe, explorer.exe, winlogon.exe EVEN cmd.exe) would not start during bootup. (and of course the "if google didnt find it, then it doesnt exsist" is a joke/exaggeration) Can someone please tell me what is going on here?
