Hi, we added 4 DSfW servers to our existing tree a couple of years ago. I've patched the servers up to OES2 SP3, but recently wanted to add a 5th DSfW server. I was doing the install on a virtual machine and got the following error when trying to install/configure OES & DSfW:

The administrator specified is not a tree administrator.
Ensure that the DSfW schema is already extended and the specified user has administrator rights on the mapped container, security container, and DNS-related contexts.

I'm using our usual tree administrator account to do the config. I have an SR open and one of the things that was suggested was to manually extend the schema. I'm not sure how to accomplish this. I think it can be done in iManager, but I'm not sure where the DSfW schema lives. Anyone else seen this?
