All of the configured XML Services for farm “Farm1” failed to respond to this XML transaction
问题描述：
事件监视器里面有2条error,分别是：
1.All of the configured XML Services for farm “Farm1” failed to respond to this XML transaction. [Log ID: df5c5a27]
2.The servers sent HTTP headers indicating that an error occurred: “401” “Unauthorized”. This message was reported from the XML Service at address “http://hostname:80/scripts/wpnbr.dll [com.citrix.xml.NFuseProtocol.RequestCapabilities]“. This XML Service could not be contacted and will be temporarily removed from the list of active services. [Log ID: 1e7d3bc5]
解决方法：
1. Ctxxmlss /u
2. Ctxxmlss /r8080(以上2步在cmd里面执行,如果是Windows Server 2008,需要注意右键选择cmd使用管理员)
3. 确认xml的端口更改为8080(AMC->Servers->EMASS->属性)
4. 发布站点的xml service 端口更改为8080
5. 服务里面手动启动Citrix Xml Service，确保服务正常启动
补充：
安装XenApp的时候建议使用8080端口，而不是与TCP/IP共享端口。
