上面已經有一篇安裝Veeam ONE的文章，根據上面文章完成Veeam ONE安裝後，點選Veeam ONE Monitor報錯如下圖所示： 上網查詢KB文件，文件連結為https://www.veeam.com/kb1580 KB文件內容如下：

Cause

Under certain circumstances, Veeam ONE Monitor Client cannot establish connection with Veeam ONE Monitor Server.

Solution

To resolve the problem, make sure that:

1. The name of the machine where Veeam ONE Monitor Server runs is correctly specified in Veeam ONE Monitor client settings.

2. Veeam ONE Monitor Server is reachable via network from the machine where Veeam ONE Monitor Client runs.

3. The user account which is used to run Veeam ONE Monitor Client is included in the Veeam ONE Users security group (at least) on the machine where the Veeam ONE Server component is installed.

4. As per Veeam ONE v6 Release Notes, in multi-Monitor Client environment, connection to Veeam ONE Monitor Server may fail with one of the following errors:

   Service connection failed Address = \\IP_Address\pipe\VeeaMDCS Error = 0xe7

   Service connection failed Address = \\IP_Address\pipe\VeeaMDCS Error = 0x5

   To resolve this issue, add the Veeam ONE Monitor Server service account to theVeeam ONE Administrators security group.

5. The ports used by Veeam ONE Monitor Client to connect to the Server are getting blocked by firewall. Make sure these ports are open on the firewall:

TCP/139
TCP/445
UDP/137

Besides these standard ports Veeam ONE Client is also using Dynamic ports in the range from TCP/49152 - 65535. Check if the mentioned ports range is open on the firewall.         鑑於本次安裝伺服器與客戶端均在同一臺機器，上面五點均被排除出故障原因，此時木頭想起是否需要在安裝完成後重啟一次，於是對虛擬機器進行重啟。幸運的是，問題真的成功解決了。回想安裝步驟中破解步驟關閉了Veeam開頭的所有程序，懷疑與此有關。經過實驗證明，出現上述問題正是因為Veeam ONE Monitor Server服務未啟動。         Veeam包括服務如下所示：
