Gary,
Open Registry Editor.
In Registry Editor, navigate to the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\ParametersSystem
Create the following value (REG_SZ): Working Directory and give it a value that points to the new database folder.
Make sure you back up the registry before you do any changes on it.
