Login problems - correct mail

I had this problem on my home network as well.  What I found was that 
when my internet connection was down (cable modem problems), that it 
would give me the errors.  What I figured the problem was is that the 
server is trying to do a reverse lookup of the client machine.  Therefore 
I set up a dns server and set up all of my internal subnet to reverse to 
names.  Since then I have not experienced the password problem.  I am not 
entirely sure that all my assumptions were correct, but the problems have 
dissappeared.
