re: MUP.sys hangs WindowsXP Saturday, January 17, 2004 at 9:14 am Windows XP Annoyances Discussion Forum Posted by Samuel Tan (1 messages posted) I'm also facing the same symptoms of the computer hanging at mup.sys on startup. My situation is as follows: When I connect my disk drives to the secondary IDE controller and leave the primary controller empty, the system boots up without a problem. When I connect my drives to the primary controller, I will hang at the mup.sys line unless I boot in safe mode. Booting in safe mode with network hangs as well. Anyway, the problem does not lie in mup.sys, but rather the stuff that gets loaded after that. Mup.sys just happens to be the last driver that's loaded that actually displays something on the screen. This can easily be verified by disabling mup.sys (as mentioned by many other people) and then the computer will just hang at the line before mup.sys. Looking through the boot logs, I compared booting up in safe mode with and without network. For my system, the additional drivers that are loaded are: \SystemRoot\System32\DRIVERS\el90Xbc5.SYS (3COM network card driver) \SystemRoot\System32\DRIVERS\rasl2tp.sys \SystemRoot\System32\DRIVERS\ndistapi.sys \SystemRoot\System32\DRIVERS\ndiswan.sys \SystemRoot\System32\DRIVERS\raspppoe.sys \SystemRoot\System32\DRIVERS\raspptp.sys \SystemRoot\System32\DRIVERS\msgpc.sys \SystemRoot\System32\DRIVERS\psched.sys \SystemRoot\System32\DRIVERS\ptilink.sys \SystemRoot\System32\DRIVERS\raspti.sys \SystemRoot\System32\Drivers\NDProxy.SYS \SystemRoot\System32\DRIVERS\rasacd.sys \SystemRoot\System32\DRIVERS\ipsec.sys \SystemRoot\System32\DRIVERS\tcpip.sys \SystemRoot\System32\DRIVERS\netbt.sys \SystemRoot\System32\DRIVERS\netbios.sys \SystemRoot\System32\DRIVERS\rdbss.sys \SystemRoot\System32\DRIVERS\mrxsmb.sys \SystemRoot\System32\drivers\afd.sys \SystemRoot\System32\DRIVERS\ndisuio.sys \SystemRoot\System32\DRIVERS\srv.sys I suppose it's one of these drivers that causes the system to hang when booting in network mode. The problem is that when the system hangs, it does not save the boot log so I have no way of checking where exactly it hangs. Has anyone seen something simliar to this?
