Win2K- Explorer.exe -Application Error on shutdown

Running Win2K Pro- Build: 2195 (SP4) on Pentium III with 256Mg memory, IE6,
MS Office 2000 Pro, Visual Studio 6 Enterprise, a bunch of other apps, plus
SBC Yahoo for internet. The machine runs fine until I logoff, or shutdown.
Then I get "Explorer.exe - Application Error. The instruction at 0x00404d51
referenced at memory 0x00000000. The memory could not be read. OK to
terminate. Cancel to debug." I've run a memory checker and it says all my
memory is OK. This has been happening for a while and I haven't really
pursued the problem because the machine seems to run fine in all other
aspects. So unfortunately I can't tell you that it started happening right
after I installed a particular program or anything like that. I tried
searching the KnowledgeBase and found numerous entries about "instruction at
xxx referenced memory at yyy" when running a particular program, but none
seemed to fit my particular situation. If anyone knows of a particular KB
article that applies to my situation, or has any insight on how I could fix
this I would appreciate it. Thanks in advance.
 
What happens if you logon as a new user? (create a new account in 'User and
Passwords'). Try a Safe Mode boot. Also try a clean boot.

Have not tried the "new user" approach, but I don't get the error on a safe
boot and shutdown. I also do NOT get it with a normal boot, no login, just
shut down. I will get the error on a normal boot, login, do nothing else and
shutdown or logoff. By "clean boot" I assume you mean booting from a power on
sequence, not just a restart. I am also looking at the autoruns utility, but
have not tried it yet. Will post results of that probably tomorrow. Thanks
again for any help you can provide Dave.

*** This helps but try the other suggestions.

*** Probably doesn't mean much.

Clean boot = no non-microsoft services at startup, no third party apps at
startup.

Error does not occur on new user. I will attempt a clean boot Monday evening
and post back. Thanks again.
 
That's probably as far as you need to go with it. The profile is damaged or
otherwise corrupt. If the profile is corrupt, you can rename the
profile(while logged on as local admin), then when the user logs on again a
new profile will be created from the image in \default user. You can then
copy over the items you need from the renamed profile. Copy the folder
contents not the folders themselves. When your sure you have all you need,
you can delete the renamed profile(s). Use the import function of your
e-mail software. Don't overwrite ntuser.dat

You da man!!!! Creating a new profile did the trick. Bizarre memory error
message is now gone! One last question. Now that I have a profile that isn't
damaged can I back it up with something like Winzip and then restore it if it
gets corrupt again instead of rebuilding all those folders? Thanks again for
all your help.
 
Probably the simplest method is to create a new user account, logon with
this account at least once then while logged on as another user with local
administrative rights Control Panel|System|User Profiles, select your
profile, Copy To, Browse to
%systemdrive%\Documents and Settings\"NewUserAcct"
Change "Permitted to use:" to "NewUserAcct" OK

Will follow your suggestion about creating a new account and copying my
profile to it. Many thanks again for your superb diagnosis and
remedies to my memory error problem. Tell your boss to give you a
raise.
