Busy NT administrators look for upgrades or drivers when they have to, when problems occur. It would be nice to be proactive and we all try. In far too many cases, there simply is not time. You can register with FileWatch.com and let it watch for updates and notify you when there are updates.

I use it to watch for updates by Dell for the various Dell servers, Cold Fusion updates, ...

Example received lately:

One or more new or updated files for products in your profile were posted at FileWatch today:

Product: Dell PowerEdge Server 1300
Name: PowerMatch for Microsoft Exchange Server Filename: pme0324.exe
File Version: 4.0
Date of File: Jan-21-2000

Description:

Microsoft's Notes from the Field are excellent.
