SYMPTOMS

You cannot enable the Network Bridge connection between network adaptors in Microsoft Windows XP. Additionally, if you type ipconfig at the command prompt, you may receive the following error message:

Insufficient system resources exists to complete the requested service

CAUSE

This problem occurs because the LogLevel entry is set to a non-zero value in the following registry subkey:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup

This problem may occur after you uninstall Windows XP Service Pack 2 (SP2) or after you install a program that changes the LogLevel registry value on your Windows XP-based computer.

RESOLUTION

Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To resolve this problem, manually modify the value date of the LogLevel value to zero (0). To do this, you can follow these steps:

Click Start, click Run, type regedit, and then click OK.
Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup
Click the LogLevel value in the right pane.
Type 0 in the Value data field, and then click OK.
Restart the computer.
