I have followed your excellent guide and it really saved the day for me.
The workstation is Win 7 64 and I moved unused "My Music" and "Contacts" across to the two mirrored sets of drives on a Win 2008 R2 server - thus preserving the Recycle Bin option.
However, yesterday, about a week after the above moves I discovered a strange anomaly on the server. When accessing the server using Remote Desktop Connection I noticed that Drive C: had 'lost' my web server folder and Drive D 'lost' my master data folder. Strangely, the correctly mapped folders were still visible and running fine when accessed via the workstation.
After the panic subsided.... I discovered that each 'missing' folders had mysteriously assumed the name of the moved folder on both drive sets - i.e Web became My Music and Master Data had assumed the identity of Contacts.
Cobian Backup is installed on the server and scheduled backups are running fine so it is still seeing the correct paths.
I have subsequently renamed the moved folders but that might have been a foolish thing to do, perhaps.
Normally the server is considered a hallowed place and system changes are very infrequent and carefully considered. The only change yesterday was upgrading MS OneDrive to 1Tb but it is only backing up a trial dataset at present.
I wonder if there are any others who have experienced this phenomenon and would appreciate any guidance. Alternatively a recommendation as to where to ask. I must add that I am a programmer and not greatly experienced in server management!
