① 我做了個自動換ip的批處理，可是運行完之後怎麼就出現：「配置的dns伺服器不正確或不存在」呢
其實沒問題，原因是命令設置dns時默認是驗證dns有效性，由於你是批處理，前面ip設置正確後電腦反應沒有那麼快不能馬上上網，此時設置dns後在見證dns有效性時基本還在未通狀態，所以會有這個提示。
解決辦法一（推薦）加上validate=no直接不驗證dns通不通。
netsh interface ip set dnsservers %NAME% static %DNS1% validate=no
辦法二 不顯示這句話的回顯（掩耳盜鈴法，其實還是驗證了）
netsh interface ip set dnsservers %NAME% static %DNS1% >nul
辦法三
設置ip後延遲幾秒再執行設置dns的語句（如果非要判斷dns是否有效的話！）
寫的這么具體不採納一下？？？
② 我有一批伺服器更改了網路環境，需要批量修改IP。現在需要寫一個批量遠程修改IP的批處理腳本。請問如何寫
ChangeIP "192.168.1.2", "255.255.255.0", "192.168.1.1", "192.168.1.1", "192.168.2.1"

'返回值說明:返回一個設置的中文說明.
