viewstate

I have had a site up and running for quite a while, but I've just started getting the MAC failed error. Quite often too. While coding tonight I've noticed it 4 times or so. The host (through someone else) changed servers and we've had a bunch of issues. This started happening since then. What are all the possibilities that it could be on the server end that I could ask? (I don't know all that much about IIS).

Thanks!
