IE and Windows Explorer hang

[Guest]

I have an app where you push a button on a page in IE, it does a SQLServer query, and displays results in an OWC chart. Works fine on several systems running various combinations of Windows, IIS, IE, OWC, etc. On one laptop, the same query will intermittenly hang. When the hang occurs, both IE and Explorer are hung. Task manager shows other processes continue to run. The system isn't dead, just the UI is hung. Not out of memory (1G RAM, 2G pagefile, both about 50% used or less). The laptop is running XP, IE 6, IIS 5.1. Have loaded all patches. Have tried reloading from recovery CD. No luck. Hang only occurs when both IE and the IIS stuff are running on this laptop. Pointing the browser to an identical instance on another system works. Using a browser on another system pointed to IIS on the laptop works. WHen the hang occurs, about all that you can do is power off. Some windows that were open before the hang are partially functional. Can't open anything else up, including popups, dialogs, etc.

Laptop has ATI video onboard. Have latest drivers. Turned off video h/w acceleration. Added DevBMP=0 to [display] in system.ini. No luck.

By accident, found that if I physically turn off the wireless adapter on the laptop, it breaks the hang and displays the "page cannot be displayed" message. I get control of the system again. If I turn off wireless and used wired connection, hang still occurs and unplugging ethernet cable breaks the hang just like turning off wireless. Hang still occurs if I disable all network adapters.

No other real problems on the system. After some of these hangs, shutdown won't complete and I have to power off. Also noticed that at the MS Update site I can download drivers, but it hangs when it gets to the installation. Have to kill the browser session. When that happens, the Properties window for My Computer won't open (nothing happens). Rebooting and repeating several times finally worked.

Tried iischagent.exe and got some data, but not sure how to interpret it. Also not sure if I just got data because of the time limit I picked. It did show the same thing as the bottom pane of IE shows when it hangs (trying to display the window with the chart).

Have commented out the code that displays the OWC chart, and the hang still occurs. At that point, the page wasn't really doing anything other than getting the results from IIS and dropping them in the bit bucket.

Been stuck for days, so any ideas, even weird ones, are appreciated! Thanks.

CWShredder told me the system was completely clean. Ad Aware found nothing
interesting, or at least nothing not present on my other systems that work OK. I let it remove everything anyway. BHODemon didn't find anything of interest.

I think I've cracked this thing, time will tell. My symptom seems to be gone, but I need to do more testing. It took two things:

1. I had the latest and greatest Zone Alarm installed (even had an update today). I had tested with it turned off, which had no impact. However, when I uninstalled it,
Windows explorer stopped hanging when IE hung.

2. I had the latest and greatest Norton Systemworks (including anti-virus), patched up and loaded. I had also tested with this turned off, which had no impact. However, when I uninstalled it, my IE hang seems to have gone away. I did this after uninstalling Zone Alarm.

I'm cautiously optimistic. I've tested for far longer than I was able to before without a hang, but occasionally the hang wouldn't happen for some time. Always happened sooner than this, though. I'll resume testing tomorrow. If you don't see another post, assume this fixed my problem. I'm bumming about the lack of protection, though....

One hopes you at least have WinXP's built-in firewall enabled, Bill.
(Having both ZA and WinXP's firewall enabled may have been your problem,
too.)

This wouldn't be the first time ZA or NSW caused such problems. Before
attempting to reinstall either, make certain you've uninstalled all
anti-virus applications and security suites which may have been installed on
the machine previously (e.g., trial versions which came with the machine).

it. Also not sure if I just got data because of the time limit I
picked. It did show the same thing as the bottom pane of IE shows when
it hangs (trying to display the window with the chart).

Have commented out the code that displays the OWC chart, and the hang
still occurs. At that point, the page wasn't really doing anything
other than getting the results from IIS and dropping them in the bit
bucket.

Been stuck for days, so any ideas, even weird ones, are appreciated!
Thanks.
