WMPNetworkSvc & WinDefend Services fail to start

[Mike]

I get an error when I boot saying that WinDefend won't load. I checked the
logs and found that both WinDefend and WMPNetworkSvc both fail to start,
errors below:

WinDefend won't start: Error 2: The system cannot find the file specified
WMPNetworkSvc: Error 3: The system cannot find the path specified

Not sure if it's related, but my Security log has several Event 5038 errors:

File Name: \Device\HarddiskVolume2\Windows\System32\drivers\tcpip.sys

Code integrity determined that the image hash of a file is not valid. The
file could be corrupt due to unauthorized modification or the invalid hash
could indicate a potential disk device error.

I'm NOT using OneCare.

Any thoughts on how to approach this one?

Thanks!

Hey there Mike,

Have you installed SP1 yet? If so, have you tried a rollback? I'm reading

Hello Mike,

I quote dean – dean --a regular contributor here:

You might try this.

Go to the main Windows Update window and
click on "Installed Updates" (on the left-hand side of the window, at the
bottom), and then remove "Update for Microsoft Windows (KB931099)" (only).

Reboot. Reboot again. (2)

Go back to Windows Update, and re-install the same
update, by clicking on the Check for Updates button.

This should essentially re-install Windows Defender on Vista.

The answer is, yes I have installed SP1, but this problem started a week or
so after installing SP1.... not right away. If I can avoid it, rolling back
is a bit too troublesome at the moment. I'd like to try other options if
there are any.

Thansk!

Thanks for the reply!

I removed KB931099 and rebooted twice. Even after checking for updates,
windows update doesn't show KB931099 as an option. I downloaded the x64
version of KB931099 from microsoft, and get the error that the update
"doesn't apply to my system". I am running Vista x64, so there's something
funky.

Is there some way to Force the update to install?

thanks!

Mike

Hello Mike,

<Is there some way to Force the update to install?>

Sure, you can try here:
64-bit <http://go.microsoft.com/fwlink/?LinkID=86955&clcid=0x409>

OR-
<http://www.microsoft.com/security/portal>

Look in the right of the page for:

Latest Definition Updates
Windows Defender
Antispyware: v1.31.9091.0
32 bit
64 bit
Information on updating Defender

Try 64 bit, or Information on updating Defender


I hope this post is helpful.

Good luck
