hard reset problem

[mhwlng]

I just tried the latest NetRemote-Suite-01-Jul-2004.exe

(WIN32)

I have several panels with the embedded web browser on it
and I load a web page with an active-x control in it.

The web page works ok.

But, if I then try to jump to a different panel (and thus unloading then web browser) my PC hard resets (xp)

This was working fine in the previous version...

Marcel

I think you have been around PPCs too long, man! :wink: Do you mean that it reboots or bluescreens?

[mhwlng]

Do you mean that it reboots or bluescreens?

I am talking about XP

and it bluescreens AND reboots

A bluescreen *always* points to a driver problem. NR will not be capable of causing this sort of catastrophe of its own accord. [I write drivers as part of my day job]. It sounds like the video driver to me. Is there anything in the event log?

A bluescreen *always* points to a driver problem.

I do not agree with you !

the blue screen indicates

PAGE FAULT in NON PAGED AREA

and it mentions win32k.sys

NR .996 didn't have the problem, NR 1.0 has the problem

No difference in PC configuration/drivers...
just replaced one version of NR with another...


Marcel

[avid]

I beg to differ. "PAGE FAULT in NON PAGED AREA" means somewhere in a driver is using a bad address, normally zero (or close to it).

If you want (and can be bothered) you can set your system to produce a C:\WINDOWS\MEMORY.DMP file via "Control Panel/System/Startup and Recovery" and set "Write debugging information" to "Kernel memory dump".

Then, after it has blue-screened, and if you want to, upload MEMORY.DMP to <http://brianavid.com/transfer> opened as a Web folder in IE. I will be happy to analyse it for you. I can't guarantee a result, but I can usually find the culprit.

[mhwlng]

again...

if I replace NR with the old version the problem is gone...

this is exactly the same on two completely different pc's with different device drivers...

how can a device driver be the problem ?

it ONLY happens if I load a web page with an active-x control on it and then exit the page...

and only in NR 1.0

In my opinion the problem must be related to how NR 1.0 cleans up the internet explorer instance

anyway..

Ben is the only one that can answer this...

Marcel,

I am very happy to accept that NR version 1.0 contains something new that is triggering the blue screen. I know from bitter experience that bugs in drivers can lay lurking for *years* before being triggered by some application calling in an unexpected way. But the real bug is in some driver somewhere. XP simply should not allow application code to do *anything* that will cause a blue-screen.

However, if there is no obvious old driver there which could be upgraded with a more recent release, then I agree that the simplest way to avoid the problem will be to get Ben to change the NR behaviour so that it no longer confuses the offending driver.

I have to agree with avid. Saying that 'it did not happen with that version but it happens with this version, therefore it must be this program that's at fault' does not always follow.

[Ben S]

If this is different in 1.0, I obviously want to find the problem.

How can I most easily reproduce this? Do you have a ccf with active x object that will definitely cause this for me?

[mhwlng]

here's an example :

http://piazza.iaehv.nl/users/mhwlng/CRASH.zip

it shows a web page with an embedded JAVA APPLET (the same problem occurs with active-x controls as well)

the java applet tries to find a webcam server on the network
you don't need to install the server app. you simply see a grey rectangle with an error message, which is what is supposed to happen if there is no server....

the PC crashes when the 'x' button is pressed to exit the panel.

load the ccf in tonto and change the URL on the web cam page to wherever the webcam.htm file is located.

O yeah... and boys : please don't say that there must be a bug in my network card driver just because the applet tries to access the network :!:

I have 3 pc's with 3 different ethernet cards and they all have the same behaviour in NR1.0...

P.S. I've been writing commercial PC applications for 20 years now,
so I have seen/caused my share of blue screens....



Marcel

[Ben S]

I can't get it to do it. Is it possible that I need to have the server, as well? It jumps back and forth fine here.

[mhwlng]

hmmm....

* I don't have the server running myself during any tests....

* are you using XP for your test ?

* are you testing it using NetRemote-Suite-01-Jul-2004.exe or are you using newer unpublished code ?

* I have the problem on 3 different pc's ?

* another static web page with the remote desktop active-x control crashes XP as well in 1.0 (not in older versions)...

Marcel,
I know this sounds simple but did you DL the NRpre1.0 again? Your first DL of the file might be "slightly" corrupt. Rare but happens.

Also, you say it occurs on 3 PC... all caused by NR pre 1.0?
Did you use the same "image" (Ghost, DriveImage, etc)for all the PCs?

[mhwlng]

Aaron,

the 3 PC's have not been changed, just NR .996 (no crash) has been replaced by NR 1.0 (crash)

the 3 pc's have not been ghosted from a common image and they do not share common device drivers.

Has anyone else, except Ben, tried my example CCF file ?

Marcel

[Rob H]

I've now tried it here under XP and I can't get it to crash either.

Video card is an NVidia Geforce 4 TI4200 with driver version 6.14.10.5672
(aka 56.72)

This is a dual CPU box

What video drivers are you using?

[mhwlng]

What video drivers are you using?

various...

tabletpc,laptop,desktop...

latest drivers available....

thanks for trying anyway...

If I am the only one with this problem (as it seems to be :D ):

I'll wait until the next NR (pre)release is out, then I will try to uninstall NR, re-download NR and try again...


Marcel

[Rob H]

Do you have anything that would be sending data to NR? If you disconnect the laptop from the network does it still happen?

[mhwlng]

just tried that...

makes no difference

Marcel

[Rob H]

Is there any software that you run on all 3 machines that doesn't come with XP? Apart from NR of course :)

What SP level of XP - I'm on SP1 here.

What plugins are you using in NR? Anything unusual?

[mhwlng]

all stock stuff as per Ben's setup program....

only JRMC plugin is used.

the tabletpc is only used for NR, so doesn't have anything else on it

all pc's are virus checked (uninstalling anti-virus doesn't have any effect)...

the latest MS security patches are installed (and SP1)

no firewall is running

Marcel

[Rob H]

One last straw to clutch at - are you running English language XP or Dutch?

[mhwlng]

U.S. :D

[Rob H]

Did you send your memory dump to Brian (avid)? That might be the only way to track this one down.
