As Carl suggested, manually forcing a static IP address through DHCP is the 
best solution.

However, if that's not an option for whatever reason, the only other option 
would be to ensure that your dhcpd service is properly connected/integrated 
with bind [named] (assuming you are using these).

Then ensure that your BackupPC server directly references the server hosting 
the bind instance referenced above.

If you still have problems, you will likely need to restart the nscd (name 
server cache daemon) on your BackupPC server before querying for IP 
addresses. e.g.: Setup a cron job.  A good way to tell if this will be 
beneficial is to hook up your laptop to the network and give it a minute or 
two to register with DHCP and DNS.  Then run nmblookup -A HostnameOfLaptop 
to see if it finds it.  If it doesn't, the above suggestion will likely help 
assuming bind is working properly.  If it doesn't work, that's an indication 
you are having problems with dhcpd and named.

The modern datacenter depends on network connectivity to access resources
and provide services. The best practices for maximizing a physical server's
connectivity to a physical network are well understood - see how these
rules translate into the virtual world?
