You guys are making this way too complicated...
Here's the breakdown. There are two parts to ASUS' WLAN Software - the driver (which allows the card to run) and the utility (which controls connections, etc). The ASUS WLAN Utility is the problem a lot of have found (causes abnormal use of resources). I recommended earlier, as I will again, to remove the Utility. Since WinXP already has a built in WLAN Utility, and is much easier to use, this will cause no problems. The problem will only arise if your dirvers get unintalled too...
For Win2K, I'm not sure how to exactly go about this, but there is a generic way to make sure any supported OS works without the ASUS Utility (except maybe 98, but what the hell were you thinking with that anyways?). If for some reason when you uninstall the WLAN Utility (Control Panel >> Add / Remove...) the drivers are not there on restart (and do not get reinstalled automatically by Windows), the reinstall the Driver/Utility package again, and track down which files are being used for drivers (Under Device Manager / Network Adapter / Properties) and make copies of them. Now uninstall it again, and on your next restart when it asks for the driver files (or if it doesn't, just install the WLAN card under device manager) point it to the folder in which you copied the WLAN Driver files to. This is simple, so please don't make it harder than it needs to be.
As always, please update your other drivers as follow:
ATI Driver: CD
MAIN INF Drivers: nvidia.com >> nForce United Driver Package (UDP)
Sound Card: Not necessary, with above installation of UDP
WLAN: CD, but uninstall ASUS WLAN Utility from control panel (fixes problem and driver files remain - only way to accomplish that)
ATK0100 ACPI Utility: CD
56K Modem: CD
LAN: CD
To make sure that the WLAN Utility Issue is gone, you can check Windows Task Manager (CTRL+ALT+DLT) and check under the Processses tab for ASWL2k.exe, IT SHOULD NOT BE THERE!
