A critical security flaw has been found in the Windows, here's a summary from AusCert:
" This security update resolves a privately reported vulnerability in the Server service. The vulnerability could allow remote code execution if an affected system received a specially crafted RPC request. On Microsoft Windows 2000, Windows XP, and Windows Server 2003 systems, an attacker could exploit this vulnerability without authentication to run arbitrary code. It is possible that this vulnerability could be used in the crafting of a wormable exploit. Firewall best practices and standard default firewall configurations can help protect network resources from attacks that originate outside the enterprise perimeter.
This security update is rated Critical for all supported editions of Microsoft Windows 2000, Windows XP, Windows Server 2003, and rated Important for all supported editions of Windows Vista and Windows Server 2008. "

It's important that ALL machines are patched and ideally, ports 139 and 445 blocked at your firewall.
An exploit already exists that has the potential to be quite nasty (it grabs details from your machine and sends them to a number of websites) and I'm sure more worms and exploits based on this flaw will appear over the next few weeks.
You can discuss this flaw in our forums here.
