When adding a new DC onto a 2008 Domain I'm told to run the adprep /forestprep command.   When I do this on the only other DC on the network I get:

Forest-wide information has already been updated.
[Status/Consequence]
Adprep did not attempt to rerun this operation.

Any ideas?

What OS are you attempting to make a domain controller? You should be running adprep from that media in its original folder or the schema update files will not be present and the update won't run.

So you have a 2008 domain what is the OS of the server you are trying to add?  

Can you check your schema version, several ways to do it   http://adisfun.blogspot.com/2013/06/windows-server-2012-r2-preview-schema.html

Thanks

I'm adding a win 2008 R2 machine.
The existing DC is a Standard SP2, not R2.

Adfind doesn't work, says it's not a program.

Ran adprep /domainprep get this:
Domain-wide information has already been updated.
[Status/Consequence]
Adprep did not attempt to rerun this operation.

You must run adprep (specifically adprep32.exe since you are running it on a 32-bit server) from the 2008 R2 media. Running your original 2008 media will not do anything because that media is too old to had the 2008 R2 schema updates.
