Does the order mentioned by Andrew correspond to the order given by 
nmblookup 'mydomain#1c'?

Playing with IP adresses I noticed that on a XP client echo %LOGONSERVER%
gives me the netbios name of the DC (PDC or BDC) which has the smallest IP.
In any case nmblookup 'mydomain#1c' outputs the PDC before the BDC.

Is this behavior expected?

Thierry.
