\work directory not found

Hi there,

We r running Windows 2003 with ERP 6.0. I had to move the instance folder from drive R: to drive C:, so I changed the Windows Service to point to the new drive and changed the entries in registry I could find, plus made changes in the SAP instance profiles. But now that I want to start up the service, it fails with an error in the Windows Event Viewer: "Unable to change to diretory R:\usr\sap\.......\work". Obviously, the work folder now sits under C:, but I couldn't find anywhere in the registry or profiles a pointer to this folder. Does anyone know how to change something to point to the new path for the work folder?
