Am I affected by the Windows Vista SMBv2 Flaw?

"The SMBv2 flaw is discussed in this security bulletin from Microsoft. The flaw was thought to allow an attacker to crash any Windows Vista computer(and pre-release versions of Windows 7) over a network. It has since been proven to allow the attacker to take over and install malware onto your PC.

SMBv2 is used to share printers and files between computers. Microsoft has not yet released a patch to fix this vulnerability, they currently recommend disabling this service. You can safely disable this service and use SMBv1 and maintain network sharing, although it may be somewhat slower. Microsoft has released an easy “Fix It” to disable the service for you.

You are vulnerable if you are running these operating systems:

Windows Vista, any service pack
Windows 7 Beta
Windows 7 RC

You are not vulnerable if you are running these operating systems:

Any of the above systems with SMBv2 turned off.

Windows XP, any version
Windows 7 RTM or Retail
