I've just installed Exchange 2003 with SP1, I already have an exchange 2000 box on the domain. When I try to replictae the folders from 2000 to 2003 it reports from the 2000 box that they are "in sync" however if I try to list folders on the 2003 box I get the error "Could not locate the root folder. Ensure that your default virtual server is running and it is configured correctly.......ID no: c103b405. I have searched high and low re this error but nothing useful so far. What I have noticed is in IIS the directory is pointing to \\.\BackOfficeStorage\domainname.com\Public Folders which I think is the problem. On the 2000 box the Public Folders directory is m:\domainname.com\Public Folders. Any ideas??
