TransactionScope报错：“与基础事务管理器的通信失败”

TransactionScope出错：“与基础事务管理器的通信失败”
http://www.cnblogs.com/Leo_wl/archive/2011/03/09/1978468.html

服务已开启
MSDTC也配好了的

A：118.123.249.*
B：118.123.15.*
这算跨网段吗？


根据上面链接里的排错方法
1.Telnet 118.123.249.* 135测试 （不能打开在主机的连接，在端口135连接失败）

居然Telnet不通
但在本机上用 netstat -a

135端口是打开的啊，为什么telnet不了啊

------解决方案--------------------
telnet不通，一切免谈
看看子网掩码和网关。
