I cannot access the internet

[crtecha]

Yesterday afternoon I lost all connection. When I looked in network connection it states

Network unavailable

The dependency service or group failed to start.

So far I've tried to netsh winsock reset

I've reinstalled motherboard drivers.

The weird thing is I can get a IP and a subnet mask but no default gateway.

I've reset my cable modem. I've changed the cat5 cable.

I did have a virus of some kind and I have a feeling I deleted something by accident using hijackthis.

I'm currently using a old hdd with a fresh load of XP sp3 on it and I have no issues.

I read that its possible that I deleted or currupted my nlavc.dll and that could be causing the issue.

I also looked through my services and most network services that are not started error out with a error that pertains to a service that isnt started or doesnt exist.

I dont have a recovery option other than a reinstall of vista. Problem I dont have my vista disk anymore. It was damaged while moving.

Any thoughts or advice will be greatly appreciated.

System Restore?

I wish I could. I used v lite for my intial install and its tweak quite a bit. So I removed a lot of features. I really have no problems reformatting and reinstalling I just feel more comfortable fixing the issue. It has me completely stumped

If you need the nlasvc.dll try this fix posted here

How to Delete/Change a System File in Windows Vista (and fix nlasvc.dll)

Warning: Do not delete system files. Bad things will probably ensue.

If you need to delete or overwrite a system file in Windows Vista, you'll quickly notice that you cannot delete system files, even as administrator. This is because Windows Vista's system files are owned by the TrustedInstaller service by default, and Windows File Protection will keep them from being overwritten.

Thankfully, there's a way that you can get around this. You need to take ownership of the files, and then assign yourself rights to delete or modify the file. For this, we'll use the command line.

Open an administrator command prompt by typing cmd into the start menu search box, and hit the Ctrl+Shift+Enter key combination.

To take ownership of the file, you'll need to use the takeown command. Here's an example:

takeown /f C:\Windows\System32\nlasvc.dll

That will give you ownership of the file, but you still have no rights to delete it. Now you can run the cacls command to give yourself full control rights to the file:

cacls C:\Windows\System32\nlasvc.dll /G your username:F

At this point, you should be able to delete the file. If you still can't do so, you may need to reboot into Safe Mode and try it again. For the filename in the example, I was able to overwrite it without safe mode, but your mileage may vary.

Oncethe file has been replace you should set the permissions back but…

TrustedInstaller does not exist in the "visible" users and groups as it runs as an NT Service so to restore:

Right mouse button click on the file and choose Properties

Click Security tab

Click Advanced button

Click Owner tab

Click Edit button

Click Other User or Group and type in NT SERVICE\TrustedInstaller

Press Ok on all dialogs until all property dialogs are closed

I have attached a copy of my nlasvc.dll from Vista Ultimate Sp1.

I was still unable to fix the issue. So I just set the drive aside. Thank you for all your help. I will update if I fix the issue.
