我通过ISA服务器进行远程应用程序连接时遇到问题：
应用程序应该通过Isa服务器连接到应用程序服务器，但是应用程序尝试通过UDP 1434连接46.x.x.x，但是ISA服务器无法像1434 UDP端口那样发布1433 TCP。

Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
