Wrong type of cassette... The older they get the more varied they become.

There are a couple "tricks" but they all involve a little bit of risk associated with doing a little bit of damage to you or the wheel.
1. The "easiest" and "lowest risk" is to take it to your LBS so that they can skin their knuckles and be put in a position to offer you a good deal or a replacement wheel & cassette if they bugger up yours.
2. The 'might makes right' approach is to slip a pair of 2' steel pipe extensions over your chain whip handles -- assuming they're the older style with narrow handles -- to increase the mechanical leverage. Of course, at this point you'd really want to have a helper to steady the wheel while you work the wrenches.
3. If you think it may be seized by corrosion or some other means you can heat the lockring and then apply some Liquid Wrench and let it soak in for a day before hitting with your chain whips again. The pre-heating helps draw the liquid wrench in as the metal cools.
4. As an alternative to Liquid Wrench, you can use a real wax candle to heat the lock ring a bit -- not so hot that you'd start to do any damage to the freehub's bear seals, etc -- and then turn the candle to a steep downward angle with the wick above the lockring and threads and let the wax drip onto the threads all the way around the lockring. Again, as with the liquid wrench, as the lockring cools the wax will be drawn in and help to lubricate the thread area to help break the lockring loose.
The are some other tricks that involve using canned CO2 to cool then heat parts to help break seized parts loose but, as I said, you can quickly exceed your comfort zone with some of this stuff. Be guided by the mantra: "Do No Harm To Yourself or Your Tandem".
