Cross-subnet network resources are unavailable for up to 10 minutes after you restart a Microsoft Windows XP SP2-based client computer (895486)

SYMPTOMS

After you restart a Microsoft Windows XP Service Pack 2 (SP2)- based client computer, cross-subnet network resources are unavailable for up to 10 minutes.

This behavior occurs if the following conditions are true:
  • The Windows Firewall is enabled on the Windows XP SP2-based client computer.
  • The Internet Control Message Protocol (ICMP) router discovery protocol is used by the Windows XP SP2-based client computer to receive default gateway information.

CAUSE

This problem occurs because the ICMP router discovery protocol packets are blocked by the Windows Firewall boot-time policy.
