I have exactly the same symptoms on HP Elitebook 6930p, Windows XP Professional 5.1.2600, Service Pack 3, interestinglysimilar setup to yours, smpreg.
Installing VMWare Player 3.0.0 build-203739 + rebooting causes this. Uninstall fixes it. I suspect the problem has something to do with the network tweaks the player installer does...
Anyone solved this kind of problem? Would like to use VMWare but this problem makes it impossible.
