Windows Zero Config Crashes on Refreshing(64bit Windows XP )

Hi,
We are using Windows XP Professional x64 Edition Service Pack 1 version
5.2.3790 and running a WLAN card driver.Right now we are facing a problem of
Explorer Crash when we try to do Refresh Network Table through "Windows Zero
Config Window" for WLAN.Its a intermittent kind of issue.
Is this a known problem with Windows Zero Config (64 bit version with XP) or
there is some issue with the OS itself.
Can somebody have any idea regarding this issue.
Thanks..
