I upgraded the main DC (ROOTDC1) in our network root domain (root.com) from Win2000 to Win2003 today. I did exactly as Microsoft said each step of the way, and everything seems to have gone fine. The only problem I have noticed is that when I open up the DNS console and browse into "_msdcs.root.com" and from there into "domains" the two subfolders have long hexadecimal names instead of what they used to have (newyork.root.com for example). Likewise if I look at the Alias records for my DCs, I see that they too have long hexadecimal names instead of saying "(same as parent folder)".
Like I say, everything seems to be working fine. I ran dcdiag and everything passed. Replication is happening OK as far as I can see. Its just this strange loss of text that I am worried about.
Does anyone know why this happened?
