Installation Error if Diagnostics Log location moved...

I was installing a new Sharepoint Server in the farm, mostly because the currently had was too small.

I ran into errors with the Office Server Web Services (it kept saying it could not find the path, although the path to that website was fine (I checked it three times). The Root virtual directory could not be found...

I tried many things. Finally I ran the Office wizard to remove the new server from the farm. I then ran it again to reinstall it (after making sure that various dbs had the Sharepoint Server as a user - see previous log). And I got the error below:

The error in the log informed me that I it was missing the location of the Diagnostics Logs that I had moved to the E: drive on the old, slow server. So I moved the Diagnostics logs to the D: drive before running the wizard to try to join the farm again. No dice. Same error. I moved the logs back to there original locale in the 12-spot. No dice.
 
I try renaming the D: drive to E: - it refuses.
 
On the point of uninstalling/reinstalling MOSS on the new server I hesitate...
 
Searching through Regedit in the NEW server (not currently on the Farm) I find an entry in HKLM\Software\Microsoft\Shared Tools\Web Server Extensions\12.0\WSS called LogDir. And guess what is in it? You got it - a reference to the entry on the E: drive...
 
Manually changed the regedit entry to match to the new d: location (on both servers) and VOILA!!!
 
So be warned - if you move the Diagnostics Logs location in a farm, a folder must be available on ALL servers (makes sense).
 
And the Office Server IIS site is gone. Probably a carryover from before...
