We use Group Policy Preferences for a lot of the settings that get delivered to users.
For one, all drive maps get set up by GP Prefs. Our usual setting is to Update for any drive map that gets created. We have discovered that in our current settings have not updated the backend SBS server name and location change as expected.
For whatever reason, the change does not seem to be taking.
So, we changed that Update setting to Replace and our new Company folder took over the O: drive letter as expected.
Note that entry number 2 is a drive map for our Companyweb site.
Once we logged off and back on again our drive letters pointed to the new SBS server destination folders.
