Hi,

I can execute the SQL statement (which involved DTC function), in the SQL
Server with Clustering service if there is no VPN server inside. But, if the
SQL Server is located behind the VPN server, those SQL statement (which
involved DTC function) cannot be executed. But, those SQL statement can run
on a standalone SQL server (without Clustering service) with/without the
same VPN server. What's wrong with my clustering SQL server? Thanks.

Regards,
Curtis
