When you confige AD DS on your Windows Server 2008 server, it automatically installs Advanced Tools. You can find them under the AD DS role in the Server Manager.
However, these tools don't include replmon.exe. But it is possible to download the Windows Server 2003 Support Tools .msi file and install it on a 2008 server. I've tested out the Replmon tool on 2008 and it worked flawless.
