Steps to setup a domain

In these days, I am preparing the env setup  for ClearCase and ClearQuest integration. Since ClearCase need a domain env to begin, I try to setup one domain and here are the brief steps.  All machines run Win2k3 server.

A. assign one machine as active directory server and setup the AD and create one domain on it.
B. on that domain controller, add DNS server role
C. add other machines to this domain. You can do this on the domain controller or the machine itself. After doing this, you can see the new domain in the logon to drop down list when you try to login domain machines.

D. in each domain machine, point to the DNS server to the Domain Controller. Else, you may encounter errors (RPC Server is unavailable) when doing step E

E. in each domain machine, add domain users or domain group into the Remote Desktop Users group. After doing this, granted domain users/groups can login domain machines
