Windows NT4 crash after Avast update

[esasse]

Today all my Windows NT4 Workstation stopped working after Avast program update.

The update is set to automatic, so today this computers updated the program to version 4.5 and asked for reboot. After reboot, I only get a blue screen with a STOP 0x0000001E KMODE_EXCEPTION_NOT_HANDLED, and I can't use the computer.

It happened with my 3 computers running NT4 Wks. First it happened with 2 machines, them I went to the third one, that was powered off. I turned it on  and logged in. Avast auto-updated itself and asked me for reboot. Then the problem happened on this machine.

I'm using Avast Professional in portuguese. All NT4 SP6 in brazilian portuguese too.

What can I do to recover this machines?

Thanks!

What file is named in the error message?

Try temporarily deleting \windows\system32\drivers\aswTdi.sys. Does it "solve" the problem? (ie. the machine boots)


Thanks

Hi,

I'm having the same Problem. I'm getting a bluescreen, every time I try to start up my NT4 System.

I've attached a picture of the BoD. Hope it helps.

Best regards,
Tobias

If you can't upload the file just send it to me email, please. Thx.

Yes, deleting \windows\system32\drivers\aswTdi.sys makes the machine boot.

Thanks for all help, I'm in direct contact with tech support.

Hi,

I can't attach a picture. Is there something wrong with the board?

Thanks for all help, I'm in direct contact with tech support.

Well, - which tech support?


Anyway, do you think you could send me a screenshot (e.g. a digital camera shot) of the BSOD?


Thanks

U got mail

Thanks, got it. BTW how much memory does the machine have? How large is the dump file (\windows\memory.dmp) if you zip it up? Do you think you could e.g. expose it on a web site so that I could download it?


Thanks.

Hi,

the machine has 128MB memory.
Unfortunatly I can't access the file memory.dmp, because Windows NT doesn't start and is the only OS on the machine.
And because of the NTFS I can't access the file with a simple DOS bootdisk. Sorry.

Is there any other way to access the file?

Well NT4 is difficult:

- no safe mode
- no recovery console


If you have a secondary computer with a cd writer, you could use the BART CD demo. But it's quite a big download (~65MB)


It's usually much easier to install a second OS (nt, 2k, xp) to a different partition and via it access the NTFS disk...

[Eddy]

You should be able to access the partition if you boot from a Windows XP/2k/2k3 cd also.

Alternitive:
add ntfs for dos from Sysinternals to the dos bootdisk and it should also work.

[Vlk]

Could you please try replacing the \windows\system32\drivers\aswTdi.sys file by this one: http://www2.asw.cz/~vlk/aswTdi.sys and see if it helps?


Thanks

Anyone else having the same problem?
We'd need to know if the problem is fixed after applying the fixed driver.

Thanks!
