I tried every possible combination. Not having the service running and running the CS ODBC enabled would cause havoc. After eliminating most of the usual suspects, I became convinced that it was a workstation install issue. Problem is that I could not test as I did not true admin rights on the server to uninstall the workstation. Earlier yesterday, the owner confirmed that all workstations were installed and that they could generate a crystal report. So I had to abort the go live (yet again). This AM, we connected so I could uninstall the client, reinstall and reboot the server. Life is back to normal and we have to schedule the go live for another day. So as it turned out, we could have pulled the trigger. Hindsight is always 20/20.
