Thanks Guys

@ John-Charles-Herzberg - i was hoping for a solution to disable all PC's via script or some other tool rather than doing one PC at a time.

@ Stampel - are you sure if we disable only server side it will not affect the local PC's

Nop It won't, SSL will fallback to SSLv2 (assuming you had SSLv2 Cypher on server side, but who would not ? And you will review this when configuring server.)

At least for IE you can run the MS FixIt or a Group Policy, as described in the MS Security Advisory at . The FixIt can be called with MSI options, I recommend /passive to not get any prompts.

As and other sources tell, you need to change the startup options for Chrome - no setting there. The best automated approach here is the described change of the registry, which can be done with a batch. The batch only acts if Chrome is the default browser.
@echo off
setlocal EnableDelayedExpansion
for /F "tokens=2*" %A in ('reg query HKCR\http\shell\open\command ^| find "Chrome" ') do (
  set val=%%B
  set val=!val:"=""""!
  reg add HKCR\http\shell\open\command /f /ve /t Reg_SZ /d "!val:-- =--ssl-version-min=tls1 -- !"

Open in new window

But: Chrome and FireFox will receive updates (if not already done) to disable SSLv3 by default.
And to use an exploit, an attacker needs local, direct access to the victim, and so needs to be in (W)LAN etc.
And of course you need to make sure that the client does not allow SSLv3 to be certain it is not used. You do not have control over all servers, and contacting any unpatched server opens the client up to the attack (if all the other requirements are met, of course). It is not safe to rely on proper server settings.

Any reason for "B" grade? I'm pretty certain my anser was worth more than that.
