在域控制器升级期间重新启动？

Question

我已经开发了一种功能，可以在现有林中提升域控制器，然后将DC从标准域控制器OU移到子OU。该功能有效，但是有时在运行该功能时，要升级的服务器将在运行该功能的大约10分钟内重新启动，而其他时候它会在重新启动之前等待大约85分钟。该功能接受CSV，以便按顺序提升多个DC。

问题是当功能在重新启动之前等待约85分钟时，它延迟了CSV中下一个DC的升级。所有域控制器都位于同一网络上的同一数据中心中。重新启动后，初始AD复制将继续进行-因此，它不必等待重新启动之前完成初始复制。

为了确保在我的客户的及时庄园中进行DC促销，我需要了解重新启动的过程。

我的问题是：什么决定了在DC促销期间服务器何时重新启动？

我的功能如下：

function New-PSATDomainController {
[CmdletBinding()]
param (
    [Parameter(Mandatory = $true, ValueFromPipelineByPropertyName = $true)][string] $VMName,
    [Parameter(Mandatory = $true, ValueFromPipelineByPropertyName = $true)][string] $Domain,
    [Parameter(Mandatory = $true, ValueFromPipelineByPropertyName = $true)][string] $ADSite,
    [Parameter(Mandatory = $true)][string] $SafeModeAdministratorPassword,
    [Parameter(Mandatory = $true)][System.Management.Automation.PSCredential] $GuestCredential,
    [Parameter(Mandatory = $true)][System.Management.Automation.PSCredential] $Credential
)

}
