What's the difference between DTCPing and DTCTester?

Question

I've used DTCTester before to diagnose MSDTC problems. However, I just noticed DTCPing seems to do about the same thing. What's the difference between these two?

From what I can tell so far, DTCPing needs to run on both client and server machines, whereas DTCTester only needs to run from the client. Are there any other differences?

Answer 1

Testing DTC settings is very common when installing BizTalk Server, so from the BTS documentation, so - from http://msdn.microsoft.com/en-us/library/aa561924.aspx

Use the DTCTester utility to verify transaction support between two computers if SQL Server is installed on one of the computers. The DTCTester utility uses ODBC to verify transaction support against a SQL Server database. For more information about DTCTester see How to Use DTCTester Tool.

Use DTCPing to verify transaction support between two computers if SQL Server is not installed on either computer. The DTCPing tool must be run on both the client and server computer and is a good alternative to the DTCTester utility when SQL Server is not installed on either computer.
