Stumped by DLL

[Zonie]

I have a client when they try to create a new folder on the desktop by right mouse click, new, folder. All the farther it gets is to the new then a error message pops stateing Explorer protection fault, Internet Explorer will be closed. In the detailed messages, SHDOC401.dll has caused a general protection fault.

Trying to create a new folder in Windows Explorer with the mouse or going to File> New>Folder creates the same error. I have scanned for Virus, Spyware and replaced the SHDOC401.dll to no avail.

Any suggestions?

Do they have hotbar?

Failing that:

This problem can be caused by an excessively long file extension entry in the registry. To fix:
- Open Regedit (Start, Run, type "regedit" without the quotes)
- Click on plus sign "+" beside HKEY_Classes_Root
- Scroll thru all the extensions (starting with ".")
- If you find a long one, right click on it and click "delete"
- Continue checking thru all the extensions listed

Thanks NooNoo, I will give this a try. They do not have Hotbar. Sorry I didn't get bac sooner, got slammed and couldn't get back till now.

.DLL dependency issues are probably one of the most frustrating aspects of troubleshooting. Fortunately, there is a freeware utility that will make short work of these types of problems. Go and download Dependency Walker 2.1 from http://www.dependencywalker.com/

This archive contains 4 files that only take up a little over 700k (so you can carry this on a floppy) and the depends.exe program has a very cool feature called Profile Module Dialog that will allow you to not only see what file dependencies and ordinals that a .dll has (any incorrect or missing files show up in red . . . this tool is damn-near idiot-proof! LOL) but also allows for you to trace every step of a process when launching the program that uses the file.

I would wager that, using this tool, you will save enough time to actually start eating lunch everyday, PLUS it will make you look like a genius (allowing you to solve issues that stump all the senior techs at your job)

A bit of reading may be required to get the hang of using all the features, but I can tell you that it is well worth the time you invest.

Try Dependency Walker & let me know what you think. It will probably become a permanent part of your toolkit.

Another vote for Dependency Walker. Very cool.

Of course, one has to know what they're looking at. It's quite... interesting how many things are dependent on one another.

Hooray and Hooray, thanks to all for the assistance, I was able to get back to this problem yesterday. I went in to the registry as per NooNoo and found (2) hotbar entries. Once these were removed, problem was gone. The client forgot to tell me they had hotbar and uninstalled it. Ok, still charged them. Thanks for the Dependecy program. I will get familiar with it and will add this to my other tools.
