how to force ssl higher encryption

we have the key from verisign, they say it will always force the client to
use 128. But the security scan guy says our site has sslv2 enabled, support
weak encryption.
Is there a way in IIS to check which version of ssl, disable sslv2? what's
the difference between sslv2 and sslv3? any documentation?
Thanks
