Limited network connectivity after expanding DHCP scope

I just expanded the DHCP pool on my windows 2003 server.  I changed my subnet mask from 255.255.255.0 to 255.255.254.0 and things seem to be working well.  My address pool is 10.0.0.1  to 10.0.1.254.

EXCEPT: users who are automatically assigned an IP address in the 10.0.1.xxx range cannot access the gateway 10.0.0.1.

What have I missed?

You did not change the subnet mask on your default gateway.

Usually the gateway has a static ip address with fixed subnet mask configured. This must be adjusted, too.

Depending on your gateway this might include a short downtime.
