Hello Experts,

My XP SP2 crashes a lot when at at LAN.

Below is the minidump analysis

An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high.  This is usually
caused by drivers using improper addresses.
If kernel debugger is available get stack backtrace.
Arg1: 00000000, memory referenced
Arg2: 00000002, IRQL
Arg3: 00000000, value 0 = read operation, 1 = write operation
Arg4: b84d3ce3, address which referenced memory

Debugging Details:

READ_ADDRESS:  00000000

looks like what causing it is the TrueVector Device Driver which is part of zone alarm (zone labs), i would suggest uninstalling and reinstalling to program so it reinstalls that driver file

go into the control panel-> add/remove programs and uninstall zone alarm, then to reinstall it either use the orginal software cd or the file that you downloaded to install the program, if you downloaded it you might want to check for an updated version and download the newest version.

It could also be a RAM problem.  It was this previous E-E thread i'd been searching for:

I do not have Zone Alarm in add and remove program list,

I'm not sure, if I have installed/uninstalled it ever by my own.

Is there can be a posiablity through which it could have installed by it self during my web access.

I might have clicked on some link and didn't noticed.

ZoneAlarm ?   Inclined to say "no way" !

After you've checked out jamietoner's comment, and if you still have an issue, there are a number of useful checks you could make by following the suggestions in that E-E thread above, it may well resolve your problem.

Does the "Cause" in this MS article, linked from the same thread, look familiar (Mylex RAID controller) ?    Will leave you to consider this for a while.

looked around a little more on vsdaatant.sys and it can be left behind after zone alram is uninstalled and can cause errors including bluescreens. also found some info on zone labs website showing what file have to be manually deleted, here's the link http://nh2.nohold.net/noHoldCust25/Prod_1/Articles55646/CompleteUninstallNonNT.html

hers some better instructions i just found to remove some of those filkes including vsdatant.sys
01.) Restart your computer
02.) When you see the screen go black and it starts booting back up keep tapping the "F8" key (at the top of your keyboard)
03.) This should bring up a menu. Choose Safe Mode off the menu by using the arrow keys on the keyboard to highlight Safe Mode and press Enter
04.) If you get a message asking to go to Safe Mode, choose Yes. If you get a help and support window, close this.
05.) Once you are at the desktop, Click Start, My Computer
06.) Click Tools, Folder Options, View Tab
07.) Place a dot next to "Show Hidden Files and Folders"
08.) Remove the check from "Hide Protected Operating System Files (Recommended)"
09.) Choose Yes to the warning
10.) Click OK
11.) Double click C:

Note: In the future steps if you do not see any files or folders, please click the "Show Files" link to view them.

12.) Double Click the Program Files Folder
13.) Right Click the Zone Labs Folder, click Delete, and choose Yes
14.) Close this window
15.) Click Start, My Computer
16.) Double Click the C:
17.) Double Click the Windows Folder (It may say WinNT if you have Windows 2000)
18.) Right Click the Internet Logs Folder, click Delete, and choose Yes
19.) Double Click the System32 Folder
20.) Right Click the Zone Labs Folder, click Delete, and choose Yes
21.) Right Click the file Vsdatant.sys, click Delete, and choose Yes
22.) Right Click the file VSUtil.dll, click Delete, and choose Yes
23.) Right Click the file VSInit.dll, click Delete, and choose Yes
24.) Restart the computer.

Thank you so much for all your efforts and I'm sorry I did not found much time to work on the steps. Today I worked out the steps you have sent.


I did not found anything with the name Zone Labs.

I have tried the steps you have mentioned but I can only see Vsdatant.sys file under system32 folder
Though, I have found "Vsdata.dll" file under system32 folder.

I have not deleted any file so far, as I'm not sure what will be the impact on my system. I do not have a backup also of my PC.

so it looks like zone alarm was on the system at one time but it was removed, so all you should need to do now is delete Vsdatant.sys and vsdata.dll they are files that  were left behind after the removal of zonealarm.

So does it mean that these files were part of Zone Alarm and not the part of windows system and dll file.

Also, do I need to remove some registery entries for them.
