从 CRM 2015 就地升级到 CRM 2016 时出现错误:“找不到网络名称”

在从 CRM 2015 到 CRM 2016(本地)的“就地升级”过程中弹出以下错误消息:

错误

Error| System.Exception: Action Microsoft.Crm.Tools.Admin.InstallSqlClrHelperAction failed. ---> System.IO.IOException: The network name cannot be found.

   at Microsoft.Crm.Setup.Shared.CrmAction.ExecuteAction(CrmAction action, IDictionary parameters, Boolean undo)

关于如何解决这个问题有什么建议吗?
