修改ad域名

# 导入Active Directory模块
Import-Module ActiveDirectory

# 定义旧域名和新域名
$oldDomain = "old.example.com"
$newDomain = "new.example.com"

# 获取当前的林根域
$forestRootDomain = (Get-ADForest).Domains.Name | Select-Object -First 1

# 修改域名
Rename-ADObject -Identity "CN=Configuration,DC=$oldDomain" -NewName "DC=$newDomain"
Rename-ADObject -Identity "DC=$oldDomain" -NewName "DC=$newDomain"

# 更新DNS记录
$dnsServers = Get-DnsServer | Select-Object -ExpandProperty HostName
foreach ($dnsServer in $dnsServers) {
    Invoke-Command -ComputerName $dnsServer -ScriptBlock {
        param ($oldDomain, $newDomain)
        $dnsRecords = Get-DnsServerResourceRecord -ZoneName "*.$oldDomain" -RRType "A","CNAME"
        foreach ($record in $dnsRecords) {
            if ($record.HostName -like "*.$oldDomain") {
                $newRecordName = $record.HostName -replace "$oldDomain", "$newDomain"
                Set-DnsServerResourceRecord -Name $newRecordName -ZoneName "*.$newDomain" -RRType $record.Type -Value $record.Value -AgeRecord
            }
        }
    } -ArgumentList $oldDomain, $newDomain
}
