SQL : The transaction manager has disabled its support for remote/network transactions

Solution:

Make sure that the "Distribute Transaction Coordinator" Service is running on both database and client. Also make sure you check "Network DTC Access", "Allow Remote Client", "Allow Inbound/Outbound" and "Enable TIP".

3. On the Action menu, click Properties.
4. Click the Security tab and make the following changes: In Security Settings, select the Network DTC Access check box.
   In Transaction Manager Communication, select the Allow Inbound and Allow Outbound check boxes.
