I have inherited a network with two servers running SBS 2003. Could the existence of these two servers on the same network be a potential problem?

If they are appropriately configured, no.

SBS MUST be the FSMO master DC of its domain.  Therefore, you cannot have more than one SBS server per domain.  When multiple SBS servers are on the same network, they must all use STATIC IP addresses (or at least static DNS addresses) (Technically, ONE of the SBS domains COULD run DHCP and the other domain(s) could be entirely static).

right now they have static IPs and the DHCP is on a Sonicwall.

You will see conflict with the DHCP on both SBS servers which is why the sonicwall is being used.  Apart from that there should be no problem as long as they are different domains.

MAKE SURE DNS is configured properly.  The clients of each SBS need to point ONLY to their own SBS server for DNS - if they point elsewhere, including to "independent" ISP DNS servers, then your users could have frequent or intermittent problems with slow logons and finding network resources.
