Seems that there is a lot of confusion for people who manage windows/IIS servers and need to disable SSL 2 and older weaker encryption. There are are few nice articles, but can sometimes be confusing unless you really know your way around the Windows Registry. I hope I can simplify this for some people.
Important: There is no need to purchase a utility to do this. Save the money. Some companies charge you $20 or more per server to have a utility to easily click and enable/disable these services.
Ok here is the help. For techies who want reference material, here is the good stuff:
The easy part: I have created a .reg file you can download and merge on your windows 2003 server that will disable ssl2 and weak ciphers. Important: This works for me, your mileage may vary. Always backup first. I won't help you if you break your server because you didn't do a backup first. You can test your server to see if you have SSL2 still enabled by going to here: http://foundeo.com/products/iis-weak-ssl-ciphers/test.cfm Download: disable_weak_ciphers.reg (downloads as a text file, then rename it to have a .reg extension)
Download this file, rename it to have a .reg extension, right click on it and merge it into the registry. Then do a reboot and when the server comes back online, test again with the above link -- SSL2 should be disabled.
Tweak as you like, no warranty! no warranty! By using this you indemnify me from any liabilities!!!
