MSDTC on server 'server is unavailable'

Question

I get this weird error on SQL Server. And I cannot find solution in older posts.

I have this procedure:

create proc _upJM_SyncAll_test
as
begin
             


        

Answer 1

In my case I had a named instance of Microsoft SQL Server at a remote server and the error output of my application looked like this:

System.Data.SqlClient.SqlException (0x80131904): MSDTC on server 'SERVER\INST_NAME' is unavailable.

Experimenting with the SQL connection string, such as replacing the SERVER\INST_NAME with SERVER,TCP_PORT_NUMBER did not help. I was still getting the same error and I decided to install a default instance (MSSQLSERVER) so that the SQL Server name became SERVER only. This solved the problem as the RPC and MSDTC started resolving the name.
