Why?  Because Microsoft says so.

Match #1.  Bullet #3 right at the beginning.

May I ask why you think he needs to upgrade his DC to Windows 2003
Server? I don't recall RPC over HTTP documents on Microsoft's site
saying that it won't work on Windows 2000 Server acting as a DC.

You only have to upgrade one DC to 2003, but you will also have to buy
new Windows 2003 CALs for all client computers.

It's pretty simple really.  If you want the new features, you have to
pay for them.  If the benefit doesn't justify the expense, then you do

so in my case i'm in a tough spot because:

1. i have only 1 exch 2003 server (and client is too small to justify
2. both DCs are win2k sp4

So, it looks like the net/net is that we can't run rpc over http unless
we upgrade the DCs to 2003 - provide for a 2003 global catalog.

do you see a simpler alternative than planning to upgrade the 2 DCs to
Windows 2003?  given the info provided.

thanks much-byron
