how to fix SSL/TLS use of weak RC4 cipher

-

please see below mentioned microsoft link

 

http://support.microsoft.com/kb/2868725

 

have followed , updated system updates. necessary updates mentioned in above url have been applied.

 

however, thing left below mentioned registry entries:

 

  • [hkey_local_machine\system\currentcontrolset\control\securityproviders\schannel\ciphers\rc4 128/128]
    "enabled"=dword:00000000
  • [hkey_local_machine\system\currentcontrolset\control\securityproviders\schannel\ciphers\rc4 40/128]
    "enabled"=dword:00000000
  • [hkey_local_machine\system\currentcontrolset\control\securityproviders\schannel\ciphers\rc4 56/128]
    "enabled"=dword:00000000

please provide input on case 

is server behind application firewall @ all? ensure there's no layer in between , client supports ciphers. can double check list of ciphers using nmap --script ssl-enum-ciphers

i'm sure had restart server after making changes registry. has server been restarted?
