IE 7 stackhash errors and ntdll.dll could be involved

me too · 03-10-2007

I've been experiencing annoying IE 7 crashes and they always happen within
seconds of downloading certain pages. I say "certain" since the crashes are
random but there are particular pages I absolutely cannot download due to
crashing. I've tried reseting IE, using 32 and 64 bit versions and using the
no add-ons option without success. Here are the two errors I see once a page
has crashed:

The fault module is either stackhash_5255 or stackhash_86fb:

While viewing application error reports using event viewer I noticed a long
list of errors that were logged the same time I experienced the crashes with
IE but where the fault module name would be listed there is a file named
"ntdll.dll":

iexplore.exe
7.0.6000.16512
468076aa
ntdll.dll
6.0.6000.16386
4549d372
c0000374
00000000000c87b7
e48
01c8051ce132328b

All the IE errors in event viewer (63 in five days) display ntdll.dll in
this manner. I yahoo'd this file and found an interesting link to microsoft:

http://support.microsoft.com/kb/261317

I read the info at the site but vista isn't listed in the "applies to"
section. I do have a core2 duo so I'm thinking a fix for ntdll.dll might
apply to me. Does anyone have suggestions or a solution?

This is a crash in nvappfilter.dll , isn't it? Is that DLL on your system?
What does it do?

That looks like you have nvappfilter.dll on your system. Who made that
file, and why is it on your system? If you upgrade or uninstall that, does
the system then work properly?
