Hi!
I encountered same problem also.
ODBCQuery: SQLSTATE: 08S01. Error: (121). Msg: [Microsoft][SQL Native Client]TCP Provider: The semaphore timeout period has expired.
ODBCQuery: SQLSTATE: 08S01. Error: (121). Msg: [Microsoft][SQL Native Client]Communication link failure.
ODBCQuery: SQLSTATE: 08S01. Error: (10054). Msg: [Microsoft][SQL Native Client]Communication link failure.
Please if there's anybody might share what's the cause of these errors... and Hope to hear any solutions that you might suggests.
Thanks.
