> I'm running WIN98, and I installed winpcap v2.1 Beta.

The current non-beta version of WinPcap is 2.2; WinPcap 2.1 beta is out
of date.

You should uninstall WinPcap 2.1, *and* make sure that there is no
"Windows\Packet.dll" file, as per an entry in the WinPcap FAQ:

	http://www.wiretapped.net/security/packet-capture/winpcap/misc/faq.htm

(the main site is down, so I'm using the mirror site); that entry says:

	Q-2: How can I see if WinPcap is installed on my system? How can
	I remove it?

	A: WinPcap 2.1 or newer: go to the control-panel, then open the
	"add/remove programs" applet.  If WinPcap is present in your
	system, an entry called "WinPcap" will be present.  Double-click
	on it to uninstall WinPcap.
	WinPcap 2.02 or older: go to the control-panel, then open the
	"Network" applet.  If WinPcap is present in your system, an entry
	called "Packet Capture Driver" will be listed (in Windows NT you
	have to choose the "Services" tab).  Select it and press
	"Remove" to uninstall WinPcap.

	To be absolutely sure that WinPcap has been installed, please
	look at your system folder: you should find files called
	packet.* and wpcap.dll.  Please check the file dates: these
	should be compatible with the WinPcap release dates.

	IMPORTANT NOTE: sometimes, when uninstalling WinPcap version
	2.02 or older from the control panel's network applet in Windows
	9x, the file Windows\Packet.dll is not deleted.  You must delete
	this file manually, otherwise version 2.1 will not work properly
	and could cause system crashes.

Once you have uninstalled it, *AND* deleted "C:\Windows\Packet.dll" if
it's present after uninstalling WinPcap, download and install WinPcap
2.2:
