We currently have a Windows 2000 sp4 Server Domain and are thinking about DCPromoing a new 2003 server to a Domain Controller and updating our Active Directory Schema but have our Primary Domain Controller and License server remain on our Windows 2000 server. Also, we have an Citrix Metaframe XPe FR 3 SP 4 server farm, is there anything I should be aware of in doing this? I have heard somewhere that licensing can be a problem is that true? Are there any documents that I should read / look at about this issue?
