What's windows xp's wzc??? Turning off identifier broadcasting means
someone snooping on your network needs to already know the name of your
network to access it. If you broadcast your network identifier, than anyone
can see it's there. I turned off identifier broadcasting and I have no
problems with my network. Here are some links that direct users to turn
this feature off for security:
http://csrc.nist.gov/publications/nistpubs/800-48/NIST_SP_800-48.pdf
Disable broadcast SSID feature. The SSID is an identifier that is sometimes
referred to as the "network name" and is often a simple ASCII character
string. The SSID is used to assign an identifier to the wireless network
(service set). Clients that wish to join a network scan an area for
available networks and join by providing the correct SSID. The SSID,
typically a null-terminated ASCII string, has a range from 0 to 32 bytes.
The zero-byte case is a special case called the "broadcast" SSID. A wireless
client can determine all the networks in an area by actively scanning for
APs with the use of broadcast Probe Request messages with a zero SSID. The
broadcast SSID probe triggers a Probe Response from all 802.11 networks in
the area. Disabling the broadcast SSID feature in the APs causes the AP to
ignore the message from the client and forces it to perform active scanning
(probing with a specific SSID).

http://netsecurity.about.com/cs/wireless/a/aa112203_2.htm :
Disable Identifier Broadcasting: Announcing that you have a wireless
connection to the world is an invitation for hackers. You already know you
have one so you don't need to broadcast it. Check the manual for your
hardware and figure out how to disable broadcasting.

The SSID also serves to reveal the location of your network to anyone with a
wireless network adaptor, which can lead to security concerns. Several
manufacturers allow the disabling of SSID broadcasts on their wireless
routers and actions points. This increases the security of your network by
making it less visible to casual eavesdroppers and users or wireless network
location software.
I think I've made my case.
