I FINALLY decided to get off the old Mindspring dial-up and took advantage
of Comcast's latest incentives for high-speed access. Got my Motorola SB5120 cable modem and Comcast install kit yesterday, read the doc and proceeded with the cable modem and modem driver installation for use with
a USB port. That's where it all went wrong.....

PC is a Dell XP450 running Win98, has always been extremely stable.
IMMEDIATELY after installing the SB5120 driver from the installation CD,
programs started aborting with "..has performed an illegal operation...will
shut down...". First to go was MSREXE, then anything that invoked IE or
Window Explorer, then almost anything else.

I followed the procedure to uninstall the driver and unplugged the modem,
but the problem remains. Comcast tech support was of no help and now the
old dial-up software won't work (all programs ultimately get the ill-op) so I can't get online from home at all.

All this from just installing the driver...I didn't even get as far as installing
Comcast's software!!

Any ideas?? Am I SOL?? Is my registry fouled?? At this point, I'm ready to
clean out the hard drive and re-install Windows...unless anybody has some ideas.

Thanks for your time.

Are you running Windows 98 Second Ed? If not this may be your problem. Earlier versions of Win 98 did not work well with usb.

Check with the Comcast and see if you can get a ethernet modem. Your machine should have no problem with an internal network card.

Thanks for the reply....

It is 2nd Edition, with Microsoft updates current as of two months ago.
Previous USB devices (scanners, digital cameras) worked fine on this PC.

And yes, a network card would probably work very well, but my larger problem
is determining what's causing programs to abort with "illegal operation" even
after I've removed the cable modem and driver that triggered this mess in the
first place. Installing a network card at this point would be useless, my PC is effectively dead in the water.

Try going to a dos prompt and type scanreg /fix

This may let you go back to a registry copy that was not messed up.

First rule of cable modem and dsl services, do not install any software they send!

Second rule, do not install any router wizard software that comes with routers.

Third rule, never use USB for a network connection.

Fourth rule, always use a router behind any modem, especially DSL.

These rules do not help you at this point.

I would delete any of the software you can find. Also make sure you check under Programs to see if there is an un-install utility in the Motorola software folder.

You may want to run a Registry Cleaner as well?

Good tips, but no success so far.

scanreg /fix didn't help, and the most recent registry backup is a couple
years old....I'll revert to it as a last resort.

I will DEFINITELY get a network card and use that if/when I get my PC back
in order.

As far as not using the Comcast software, no problem there, I never
got as far as installing any of it. The ONLY SOFTWARE INSTALLED was the cable
modem USB driver...which I've already removed...but the damage is done,
msrexe and other programs still abort with "illop" and my old dial-up
software won't work anymore...the modem dials out fine but the software can't locate the servers, then all related programs abort with "illop"!!!!!

Any/all advice is welcomed...if I don't figure something out soon I'll likely
just back up what I can, scrub the disk and reinstall Windows from scratch.
I hate to do that, it sounds too much like work.

A quick Google from my PC at work turned up thousands of references
to MSREXE such as the following:

"Added to the system as a result of an ICQ Trojan that alters Win.ini and System.ini files and generates several. .exe-files with randomly chosen names"

It would seem that this is a virus program that has probably been resident for a while and
finally launched itself when I installed a network device. Clever *******.
I found helpful removal clues at http://www.hackfix.org/subseven/fix2.1.shtml,
among others.

If removing this thing resolves my errors, I'll report back here.

Got rid of the MSREXE over the weekend, but it turns out it was a
non-destructive virus and not related to my problems. Also ran scandisk
and any other diagnostic tool I could find and found zero problems.

HOWEVER...it appears that all programs getting the ILLEGAL OPERATION are those
that include networking-type capabilities...that is, some form of network or
internet or dial-up capacity.

I pulled up the "Driver File Details" for the Dial-Up Adapter (under
My Computer->Properties) and used Windows Explorer to look at
the properties for all of the .vxd and .386 system files listed. Curiously,
many of them have "modified" dates in the area of 1999, but "created"
dates of 11/2/2005 (!!) which is when I installed and removed the USB driver
and my problems started.

I'm assuming at this point that these network drivers were either reloaded or
reregistered on 11/2/2005, causing the "created" date to be updated. I'm
ALSO assuming that they were reloaded improperly or maybe something dropped out altogether, and is causing a memory conflict between two drivers.
I assume that's what is causing the illegal operations...two drivers accessing
the same part of memory.

Anyone know where I can go from here? Is there a good way of reloading these dial-up adapter files? Anyone know where they came from in the first place? This is getting interesting, but I (and my family) really want our
internet access back!!

See if you can roll back the drivers. I can't remember if 98 has the ability to roll back drivers??

That's exactly what I want to do. I suspect I MAY be able to do that with
Add/Remove programs, not sure...I quit late last night before trying it.

One more possibly important clue I left out...for kicks, I ran the Internet
Explorer Repair tool, and it came back with:

"Internet Explorer 6 cannot be repaired due to the following errors:
Version 2.0.7024.0 of file ATL.DLL exists, but the version needs to be
greater then 3.0.8449.0"

ATL.DLL is another of those files that shows a "modified" date of 1998, but
a "created" date of 11/2/2005...when my problems started.

I may be wrong, but it seems as though a number of network-related library files were reverted or overwritten and I need to put them back.

IE Fix

Might sort something for you?

I can't remember on Win98, but on 2k and XP you go to the device manager and roll back the drivers.

Resolved.

I had conflicts between network and dial-up drivers...still not sure EXACTLY which ones, I'm guessing the "accelerator" drivers. Tried uninstalling (Control Panel->Add/Remove Programs->Add/Remove System Components) the dial-up adapter drivers and reinstalled them (turns out many came from the Earthlink dial-up install CD) and had same problems. Then I went through several iterations of "what if I try this...".

In the end I had to uninstall all Earthlink software used for dial-up, uninstall Sygate Personal Firewall, then reinstall dial-up adapter drivers so we can retrieve the last of our email from our Earthlink account before we terminate it.

I then reinstalled the cable modem drivers, loop-back tests passed, and after being on hold with some very uninterested Comcast tech support people for about 20 minutes, they activated my account. We're now online at ridiculously fast speeds and all program errors are gone. :smile:


Cheers.
