MSDTC无法PING通的问题

[hunhunnowant]

在两个局域网各自的电脑中，用一个DTCPING的工具都能ping的通。但想从一个局域网A的电脑上去ping局域网B的电脑时，就ping不通。

一端提示为：
DTCping server is ready to take incoming calls
RPC server received call from client
gethostbyname can not resolve RFZAPPS2

另一端的提示为：

谁能告诉我怎么回事？是不是在防火墙上什么设置错了？？？？

[icuc88]

不能有防火墙！！！

[hunhunnowant]

不可能不用防火墙的,两个地区的部门之间的信息传递阿.关键是要怎么设置呢?

[mudonfield]

你的局域网A和局域网B如何连接的，防火墙怎么架设的？
