KB文档内容如下：

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 Administratorssecurity 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.

        鉴于本次安装服务器与客户端均在同一台机器，上面五点均被排除出故障原因，此时木头想起是否需要在安装完成后重启一次，于是对虚拟机进行重启。幸运的是，问题真的成功解决了。回想安装步骤中破解步骤关闭了Veeam开头的所有进程，怀疑与此有关。经过实验证明，出现上述问题正是因为Veeam ONE Monitor Server服务未启动。
