Hey Jason,

   If you ask me the workstation account was not created or not  created
correctly on the PDC. 

I cannot think of any other reason why this message would pop out.

As far as the .SID & .mac files go, one of them gets updated whenever the
workstation chasnges its trust account on the server (by default its 7 days if
memory serves). The .mac file is the identifier for the PDC and I don't think
it changes but I could easily be mistaken.
