This comes from a bad install of a networking component. Go into network properties and remove EVERYTHING (if you just pull the adapters, it will take the rest with it). Reboot and reinstall your adapter. If the install goes cleanly, it should fix your problem.
Install and remove network components. To do so, follow these steps:
1. In Control Panel, double-click Network.
2. Click Add, click Adapter, and then click Add.
3. In the Manufacturers box, click Detected Network Driver. In the Network Adapters box, click Existing NDIS2 Driver, and then click OK.
4. If you have not entered a workgroup name and a computer name previously, you are prompted to do so. If you are prompted, fill in the appropriate fields on the Identification tab.
5. Click OK or Close until you return to Control Panel. When you are prompted to restart your computer, do so.
6. In Control Panel, double-click Network.
7. Click the network adapter, and then click Remove.
8. Click OK. When you are prompted to restart your computer, do so.

When you restart your computer after installing the Dial-Up Adapter, you may receive the following error messages:
Cannot find a device file that may be needed to run Windows or a Windows application.
The Windows registry or SYSTEM.INI file refers to this device, but the device file no longer exists ...
If you still want to use the application associated with this device file, try reinstalling that application to replace the missing file.
The following files are listed as missing:
Two additional dialog boxes may appear informing you that the following two files cannot be found:
After you acknowledge these error messages, Windows starts normally but without Dial-Up Networking functionality.
This problem can occur if you install Dial-Up Networking, Dial-Up Adapter, or Virtual Private Networking and then cancel Setup while the Copying Files dialog box is displayed. The Dial-Up Networking files are not copied to the hard disk but the file names are added to the registry. When the computer is restarted, the files are requested and cannot be found.
NOTE: If you have previously set up Dial-Up Networking and have added items such as phone numbers, TCP/IP settings, and other protocols, record the information before you remove the Dial-Up adapter. Do the same for Network Adapter properties information if a network adapter is listed in Network properties. To resolve this problem, remove and then reinstall Dial-Up Networking. To do so, follow these steps: 1. Click Start, point to Settings, and then click Control Panel.
2. In Control Panel, double-click Add/Remove Programs.
3. Click the Windows Setup tab, and then click Communications.
4. Click Details, and then click to clear the Dial-Up Networking check box.
NOTE: If you receive the Ndiswan.vxd error message, click to clear the Virtual Private Networking check box only.
5. Click Close, click OK, then click Apply.
6. When you are prompted to restart Windows, do so.
7. Click Start, point to Settings, and then click Control Panel.
8. In Control Panel, double-click Add/Remove Programs.
9. Click the Windows Setup tab, and then click Communications.
10. Click Details, and then click to select the Dial-Up Networking check box.
NOTE: If you cleared the Virtual Private Networking check box in step 4, click to select it.
11. Click Close, and then click OK.
12. If you are prompted to restart Windows, do so.
If any additional protocols are necessary, add the protocols by using the Network tool in Control Panel.
NOTE: Check with your system administrator or Internet service provider to determine the required settings for Dial-Up Networking and TCP/IP.
Look for the same keys to see if you spot them
Use Registry Editor to delete the StaticVxD value in the Vnetsup subkey under the following registry entry: HKEY_LOCAL_MACHINE\System\CurrentControlset\Services\VxD\vnetsup
Use Registry Editor to delete the StaticVxD value in the DFS subkey under the following registry entry: HKEY_LOCAL_MACHINE\System\CurrentControlset\Services\VxD\dfs
Needless to say, if you do not see the exact same keys, leave well alone
