Dean,
You would really want to post this to the Small Business Server news group.
They have all the experts ( like the fabulous M&M girls ).
As far as I know, there should be no problem doing this. You can have as
many Domain Controllers as you want in a SBS environment provided that the
SBS box is the first Domain Controller and that the SBS box holds all five
of the FSMO Roles ( might want to check on this one.... ).
Now, your question is probably about extending the schema ( from WIN2000 to
WIN2003 ) and the potential problem with Exchange 2000 ( the 'mangled
attributes' problem ). Not sure. Would not see why SBS2000 would be any
different than 'normal' WIN2000. But, SBS is a different animal so I would
post in the SBS news group.....just to be safe.
