Yes, we do have firewall.

BTW, the issues have been resolved after I applied Windows 2003 Service Pack 1.  It seems that this is Microsoft's issue.

Thanks!

This is problem in clustering.  I did not realize it was fixed in Service Pack 1.  The way to fix this issue pre-SP1 is by going into the Windows Registry and disabling DHCP Media Sense.
 
The MSKB article can be found at http://support.microsoft.com/kb/q239924/.
 
1.Use Registry Editor (Regedt32.exe) to view the following key in the registry:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters
Add the following registry value:
Value Name: DisableDHCPMediaSense
Data Type: REG_DWORD -Boolean
Value Data Range: 0, 1 (False, True) Default: 0 (False)
Description: This parameter controls DHCP Media Sense behavior. If you set this value data to 1, DHCP, and even non-DHCP, clients ignore Media Sense events from the interface. By default, Media Sense events trigger the DHCP client to take an action, such as attempting to obtain a lease (when a connect event occurs), or invalidating the interface and routes (when a disconnect event occurs).2.Restart your computer.
