使用 PowerShell 检查 AD 中是否存在组

我想为该组创建代码来检查该组是否存在。但是，我无法开始工作，因为它成功地将用户和组的部分成员仅添加到一个组中，而不是其他组，因为我设法在活动目录中创建一个组并从 csv 中读取。这是我的代码和结果。似乎在成功添加用户并添加组成员后我总是收到错误

正如您所说，用户已成功添加到 AD，然后只有您收到错误。因此，您可以使用两种方法来避免该错误。您可以尝试使用

Get-ADGroupMember -Identity $groupmember -Recursive | Select -ExpandProperty SAMAccountName | -ErrorAction SilentlyContinue

或者你可以尝试这样

try {
Get-ADComputer -Identity “something”
}
catch [Microsoft.ActiveDirectory.Management.ADIdentityNotFoundException]
{
Write-Warning “AD computer object not found”
}
catch {}
