批处理文件：IF ELSE 的语法

Question

我的环境中有一台旧的 Windows Server 2000 服务器，它不会针对服务器 2012 DC 进行身份验证。当我们升级此服务器时，我必须确保它始终指向 Server 2008 R2 DC。我想出的最佳解决方案是一个基本批处理文件，我将每 5 分钟运行一次（计划任务），以首先检查它指向的 DC，并在必要时进行更改。我还想将这些记录到一个标有时间和日期的文本文件中

我知道我要编写的脚本，但不知道批处理文件中用于 IF ELSE 的语法。你可以忽略命令实际上在做什么我对语法更感兴趣

我尝试用 JavaScript 编写脚本

if(nltest /server:ServerName123 /sc_query:branch === DCName01) 
{
\\I would like it to do nothing apart from write to a text file that it succeeded

    Print to a text file ("Ponting to DCNAME01 with time and date");
{
else
{
\\I would like it to run the following command to point the server to the correct DC

nltest /server:ServerName123 /sc_reset:branch\DCName01;
Print to a text file "("Changed to DCNAME01 with time and date");
}

谢谢

@echo off

rem set nltest query result  to variable
for /f "tokens=* delims=" %%# in ('nltest /server:ServerName123 /sc_query:branch') do (

    set "nlquery=%%#"
)


if "%nlquery%" equ "DCName01" (

    echo Ponting to DCNAME01 with time and date >some.file
) else (
   nltest /server:ServerName123 /sc_reset:branch\DCName01
   echo Changed to DCNAME01 with time and date >some.file   
)

编辑 - using conditional execution

@echo off

nltest /server:ServerName123 /sc_query:branch | find /i "DCName01" 2>nul 1>nul && (
    echo Ponting to DCNAME01 with time and date >some.file
) || (
    nltest /server:ServerName123 /sc_reset:branch\DCName01
    echo Changed to DCNAME01 with time and date >some.file  
)
