Note: This is a part of a collection of posts that deal with fixing internet problems. Each post will address a different problem and provide a fix.
One reason you might find that your internet does not work is because of a faulty uninstall of Norton (sigh -that software never seems to catch a break.) What seems to happen is this:
- You uninstall Norton.
- Norton leaves parts of itself in the registry.
- ???
- Your Internet breaks.
The problem here is that Norton leaves keys in the registry that try to load the Norton program before they load internet services. Many firewall programs do this to make sure that protection is loaded before internet connection is established. The problem here is that the Norton uninstaller does not remove these keys. Windows will just freeze the internet connection process after it fails to load Norton.
There are two ways to fix this:
- Run the Norton Removal Tool. It’s much more thorough then the included uninstaller and should delete the keys that were left behind.
- Manually edit the registry.
The following steps will allow you to fix the problem through the registry:
- Open up the Registry Editor.
- Navigate to the following key: “HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\DHCP”.
- Open the value “DependOnService”.
- Delete any references to “SYMTDI” or “NISDRV”.
- Navigate to the following key: “HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\NetBT”.
- Open the value “DependOnService”.
- Delete any references to “SYMTDI” or “NISDRV”.
And that’s it!
NOTE: Thanks goes to the author of this site for providing a fix to this problem.
How to explain this problem to the client: The uninstall of NAV did not finish completely and left parts of itself in your computer. These parts broke the internet connection process. I simply removed those faulty parts.
Good luck and tell me how it goes on the forums.
