Missing Public and Exadmin directories

[POSAPAY]

Hey,
I just installed Exchange2003 on a win2000 box, and for some odd reason, under IIS (as well as couple of other places) the error is:

The system cannot find the path specified.

I checked.. in IIS for public folder, and it sais the path to be: \\.\BackOfficeStorage\COMPANY\Public Folders

I don't have BackOfficeStorage folder anywhere on the installation harddrive. I didn't see it anywhere on C dirve either.
I've installed pretty much everything on drive D:I went through I think all the steps of Exchange2003 preps and installation steps. Yet I'm missing these two folders.
Other then these, Exchange seems to be working.

Any idea why I'd be missing "BackOfficeStorage" ??
Recommendations?

Thanks!
Regards,
