The Benefits of WSUS
- Save bandwidth, because only one machine downloads your updates and distributes them instead of each computer downloading updates individually.
- Save Time, because you manage all of your computers from one place instead of going from computer to computer.
- Better Security, with WSUS your control over the updates will be vastly improved and therefore your network will be more secure.
- MMC console instead of Web interface
- Better reporting tools
- More options and settings
- You can't sync a WSUS3 Server with a WSUS2 server
- The MMC console is terribly slow over a WAN connection.
- There is no web interface, so you have to install the MMC snap-in and the Microsoft Reporting tool in order to manage your server from another computer.
