Cris is pointing out a more fundamental problem, that of updates. The patch to address conficker was released in October08.

Sadly, this customer neglected the importance of keeping the anti-virus current. They now suffer the consequences with conficker already causing major disruption... To this point we see no other objective solution except to format all worksratins...they also bought the anti-virus renewel...
Thanks,
Dan

personally my preference is hardware firewall that does UTM so it never gets inside the network...
And closing port 25 to workstations only really prevents them from sending it back out.
As long as the server and all workstations are fully patched(the conflicker patch came out around 6 months ago), conflicker shouldn't be an issue.

This link mentions ISA 2000 but the theory is the same

Hi all,
How do I close port 25 on my internal network? and allowing ONLY the SBS
2003 Server?
The server is SBS 2003 R2 with 2 NICs and ISA 2004 installed...all SPs
applied.
Thanks,
Dan
