Dear Experts,

WEe have a Vista Home Premium Edition w Symantec 2010 Security Suite
User is unable toc onnect to the internet wired or wireless (unless if IP is statically assigned).
Network Connection icon in the system tray  shows "Connection Status: the dependancy service ir group failed to start"
I ran SFC /scannow command that didn't help.
Then I found this link: http://social.technet.microsoft.com/forums/en-US/itprovistanetworking/thread/bf4f3d94-09ca-4549-abe1-bfa3aae90458/

and tried the following, but it didn't help.
takeown /f C:\Windows\System32\nlasvc.dll
cacls C:\Windows\System32\nlasvc.dll /G "user name":F
Deleted the nlasvc.dll and replaced it

I checked and the following services are not running and also fail to start:
DHCP, Network Location Awareness

I haven't tried to repair Vista using the Vista disc as I don't currently have a Vista Home Premium Disk. Can anybody please help me out.
I think I also need to replace the wininit.exe

I tried to start the services manually.
NLSA service failed with: Widnows Couldn't start the network location awareness service on local machine. Error 5:Access is denied"
DHCP client errored out with the same error message.

Not exactly. Symantec was already installed, well for almost a year before this issue. I tried disabling the Symantec AV and the firewall, but still have the same issue.... I also checked in quarantined items to see if the file was in there, but it wasn't.
This a Vista Home Premium, I'm still looking for the Vista disk as the user doesn't have one, so couldn't run a repair and System restore didn't work (well at lest according to the user), I will try the System Restore tomorrow if nothing else works...
I found some articles where TrendMicro corrupted that particular DLL. Trend Micro AV was never installed on this laptop, however all of the errors and symptoms are basically the same as if TRendMicro corrupted the NLASVC.DLL I guess it`s possible that Symantec may have screwed it up...

You need to download a Vista Recovery Disk or use your Vista Setup Disk to start your PC and launch system restore to go back to a restore point when there was no problem.

A downloadable version of Vista Recovery Disk is as follow.


(I assume that your computer is of Vista 32 bit.)

A tutorial of Vista Windows Recovery is in the URL below.

When a problem appears in Vista and there are no clues from google, it seems to me the last resort is to use system restore as Vista is much better in system restore than the system restore in XP. System Restore in Vista is just like a time machine to go back to the exact state when the problem does not exist. But the drawback is that it consumes a lot of hard disk apace and it will restore the applications that you have removed and old version of document on desktop,

So, before your use System Restore, make sure all user data has been properly backup as it is just too powerful if Vista thinks that the path you stored your data is part of the system folders.

In a nutshell, System Restore can reduce the time of troubleshooting (except the problem is caused by hardware failure) but it must be used with due care.

User doesn't want to use that software that you suggested.... I tried to order a Vista Home Premium OEM disc, but apperently a lot of compnies have stopped selling it without a License Key...
I was able to start the System recovery from Programs/Accessories/System Tools but it failed every time...
One of my users thinks that he has a Vista Home Premium disc at home, so I will wait on him to bring it over and will update here... I wonder if there is another way to fix it without having the recovery disc or the Vista original disc...

you can start Vista in Safe mode and use MSCONFIG to disable the Symantec service.

Then, restart Vista in normal mode to see whether the problem has solved or not.

If yes, un-install Symantec 2010 Security Suite and do a windows update, restart Vista again and install back Symantec 2010 Security Suite.

Sorry about delayed response. using System Restore disc didn't work. User asked to take the laptop home to make the backup and he decided to do a restore to manufacturer`s defaults. I haven't heard anything since, so I think he is up and running. Thank you for your help.
