PCI Scan Failing / SSL Ciphers

[John Callender]

I have a website that keeps failing a PCI compliance scan. It tells me that my SSL ciphers are below 128 bit encrytpion and that I need to disable SSLv2.0. I do not know where to go to make the necessary changes or how to do it. Will this effect any of the other sites on the server? How can I raise the SSL Cipher encryption? If someone could point me in the right direction it would be greatly appreciated. After the last change on the Plesk Control Panel I had a very long weekend and would like to prevent that this time around.

Thanks

John
