In addition to the subject behavior, when you open a CMD.EXE window and type Ipconfig, you receive:

Insufficient system resources exists to complete the requested service.

This behavior will occur if the LogLevel Value Name, a REG_DWORD data type, at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup is NOT zero (0).

NOTE: Uninstalling SP2, or a program that changes LogLevel, can cause this.

To correct this behavior:

1. Open a CMD.EXE window.

2. Type the following command and press Enter:

reg add HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup /V LogLevel /T REG_DWORD /F /D 0

3. Shutdown and restart your computer.
