當輸入正確的用戶名和密碼是總是出現(xiàn)無法登陸的情況，匿名情況下額出現(xiàn)這種提示，問題界面截圖圖下圖所示：

事件監(jiān)視器里面有2條error,分別是：

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://EMASS: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]

解決方法：

1.??????? Ctxxmlss /u

2.??????? Ctxxmlss /r8080(以上2步在cmd里面執(zhí)行)

3.??????? 確認xml的端口更改為8080(AMC->Servers->EMASS->屬性)

?

4.??????? 發(fā)布站點的xml service 端口更改為8080

?

5.??????? 服務里面手動啟動Citrix Xml Service，確保服務正常啟動

?

補充：

安裝XenApp的時候建議使用8080端口，而不是與TCP/IP共享端口。

當citrix的客戶端通過瀏覽器訪問網(wǎng)站時出現(xiàn)錯誤：he Citrix server is unable to process your request to start this published application at this time. Please try again later. If the problem persists, contact your administrator.

問題出現(xiàn)原因：

A possible cause for this issue is that the third party software installation utilizes an executable file named cmstart.exe and modified the environment variables to point to that executable. Because XenApp uses an executable named cmstart.exe for the launch of publish applications it might get confused and locate the cmstart.exe of the third party software instead. Of course by using the wrong version of cmstart.exe the launch process breaks.

One common reason why XenApp located the wrong cmstart.exe is because the third party software might have modified the environment path variables to point to its cmstart.exe. XenApp does the same to locate cmstart.exe for publish application launch process. So the variables provided by the third party software get the priority.

?

解決方案：

An easy to change resolution is to move the variable of the location of the third party software after the XenApp variables. After the change XenApp should locate the correct version of cmstart.exe
