MSDTC和防火墙 [英] MSDTC and firewall
问题描述
我们正在使用MSDTC进行SQL事务. 我在设置防火墙以使MSDTC正常工作时遇到问题. 应用程序和SQL在不同的计算机上运行. 如果我关闭应用程序服务器上的防火墙，当前MSDTC正在工作. 我认为应该为某些端口的防火墙设置添加某种例外. 这样防火墙仍然可以打开，并且DTC不会有任何问题. 我不确定要在防火墙设置中添加的端口(我确实尝试添加端口135，但未成功)
We are using MSDTC for SQL transactions. I am having issue with setting up firewall for MSDTC to work. The application and SQL are running on separate machine. Currently MSDTC is working if i turn off firewall on application server. I think there should be someway to add exception to the firewall setting for some ports. So that firewall can still be ON and DTC will not have any issues. I am not sure of the ports to add in firewall setting (I did try adding port 135 with no success)
推荐答案
使防火墙允许端口135和dcom端口范围.默认情况下，dcom端口范围是1024-65535.多数民众赞成在打开.您可以在注册表中或使用dcomcnfg限制此范围.这篇文章对此进行了描述:
Have your Firewall allow port 135 and the dcom port range. By default, the dcom port range is 1024-65535. Thats a big range to open up. You can limit this range in the registry or using dcomcnfg. This post describes this:
