Insert into linked server fails with "The transaction manager has disabled its support for remote/network transactions"
Try enabling the DTC on the sq202 box, since that is the server initiating the distributed transaction. You will also need to have Enable Promotion of Distributed Transactions for RPC option set to True as well for the sq009 linked server located on the sq202 box; when this option is TRUE, calling a remote stored procedure starts a distributed transaction and enlists the transaction with MS DTC.
