all of the Microsoft Outlook clients will look to the
Global Catalog everytime they try to do some stuff. if
you are rebooting the only GC that you have then you have
a problem. also if you only have DNS installed on your
first DC you will get the DNS "HANG". if you only have 2
DC's in your domain you will have issues because in a
windows 2000 network you need to have the FSMO role of
infrastructure master on a different server. Windows
server 2003 is not limited by this issue so if you can
upgrade your 2000 ad structure to 2003 and then go to
2003 functional level, you will have much better luck.
