Being a master or slave has nothing to do with how remote domains are 
resolved.  Master and slave only specify how your local domains are 
loaded into the server's memory.  So whatever the problem is, I think 
it's a coincidence that it's affecting the slaves and not the master (I 
guess you configured all the slaves similarly, so made the same mistake 
on all of them).

These problems are with applications running on the servers themselves, 
or with users whose resolvers point to the slaves?

If it's with applications on the servers, check their /etc/resolv.conf 
files.  Maybe the slaves are pointing to the wrong place.
