Networks

I have found:
"Cannot promote a Windows 2003 Server Domain Controller in a Windows 2000 Forest"; TechNote ID# 278875

"...adprep /forestprep Command causes mangled Exchange 2000 attribute"; TechNote ID# 314649

It would appear that 2000 & 2003 servers can coexist as domain controllers on the same domain. It requires that I update the schema on the Windows 2000 Server domain controller to match 2003. Once the schema is update I can promote the 2003 Server. The only cause for concern is my existing Exchange 2000 Server.

Here is what I must do as I understand it assuming only a single domain controller for the domain:
1.) Remove my existing DC from the network
2.) Run Inetorgpersonfix.ldf to prevent mangles AD exchange objects.
3.) Using the 2003 CD-ROM. Run adprep /forestprep
4.) Reconnect DC to network
5.) From the 2003 CD-ROM run adprep /domainprep.

Please let me know if I am correct here.

Step one above..."remove DC from network" I simply mean to disconnect the network cable not demote the DC.

I have added a Windows 2003 Server as DC to a windows 2000 DC with no problems. Generally windows 2000 server and Windows 2003 Server are the same thing, except that 2k3 has more and better features, like, Terminal server supports full color and client drive redirection, etc. There isn't anything special you have to take into account.

It can be done... just simply join the W2k3 box to the domain and make it a domain controller.
At that time you will be able to install TS 2003 licens.

Please extend the active directory schema for your 2003 server to be joined to the forest just search microsofts site for the utility.
