调研方向

从 DnsServerAddress 资源的 Test-TargetResource 路径开始,并在所述的 Windows 环境中复现 NetAdapterName/DnsServerAddress 配置。验证无效或暂时不可用的 InterfaceAlias 会将资源报告为不处于所需状态,同时不会终止 Test-TargetResource 进程。

由索引模型根据 Issue 内容生成。

描述

Problem description

Imagine a scenario where a user wants to perform both these steps in the same configuration:

  • Rename a network adapter
  • Assign a DNS server address to the same adapter

If a configuration like this is put through a Test-TargetResource phase before being applied (see example), it will fail with 'System.InvalidOperationException: A network adapter with the alias '' could not be found.'

PowerShell DSC resource DSC_DnsServerAddress  failed to execute Test-TargetResource functionality with error message:

DSC configuration
NetAdapterName "Ethernet0"
{
    NewName = "Ethernet0"
    InterfaceNumber = 1
}
DnsServerAddress "Ethernet0-IPv6"
{
    InterfaceAlias = "Ethernet0"
    AddressFamily = "IPv6"
    DependsOn = "[NetAdapterName]Ethernet0"
}
Suggested solution

The DnsServerAddress resource should not return a terminating error when the network interface specified in InterfaceAlias is invalid - instead, it should just return that the resource is not in the desired state. There is no need to tank the entire Test-TargetResource process.
