I did some research on disabling the ciphers from one of the Microsoft websites. <br />
<br />
The RC4 cipher can be completely disabled on Windows platforms by setting the &quot;Enabled&quot; (REG_DWORD) entry to value 00000000 in the following registry locations:<br />
<br />
HKEY_LOCAL_MACHINE\SYSTEM\<wbr />CurrentCon<wbr />trolSet\Co<wbr />ntrol\Secu<wbr />rityProvid<wbr />ers\SCHANN<wbr />EL\Ciphers<wbr />\RC4 128/128<br />

I made these changes and installed update <br />

I restarted the server after these changes. <br />
<br />
our customer needs to be PCI compliant. &nbsp;When i run the scan to test if still fails on RC4 CIpher<br />
<br />
is there something that I am missing?

How to disable RC4 ciphers on a SBS2011 server.

Small Business Server (SBS) is a line of server operating systems targeted at small businesses by bundling the operating system with a number of other Microsoft products that would normally need to be purchased or licensed separately. The most notable inclusions are Exchange, SQL Server, SharePoint and ISA/TMG (Microsoft's firewall and proxy server).
