Are you running the web interface on the distributed Nagios sites?  If so, 
log into both Distributed and Central web interfaces and look at the 
results side by side.

Then, try scheduling active checks through the web interface on the 
Distributed side.

Are you using nsca to send the results from distributed to central?  Is it 
configured out of inet on Central or running standalone?
