When you log on to your network on a Microsoft Windows XP-based computer that contains both a wireless connection network card and a wired connection network card, the Log On to Windows dialog box may remain on the screen for one to two minutes. After the dialog box disappears, you can successfully log on.
This problem may occur when the following conditions are true:
  • Neither the wired network card nor the wireless network card uses the Authenticate as computer when computer information is available option
  • The DHCP client assigns an old IP address to your wireless network card before authentication has finished
Note To locate the Authenticate as computer when computer information is available option, follow these steps:
  1. Click Start, and then click Control Panel.
  2. Click Network and Internet Connections.
  3. Click Network Connections.
  4. Right-click your network connection, and then click Properties.
  5. Click the Authenticate tab.
