Recommendations for automatic computer inventory [closed]

For someone looking after a small 50 Windows PC network (Mainly XP - some Vista), are there any tools that can do an automatic inventory of the network e.g.

• OS
• Memory size
• Hard drive type and size
• Serial numbers
• Monitor type

etc.

At the moment, someone has to go from PC to PC writing all this stuff down.

Solution 1:

I have heard great things about Spiceworks. Its big features are:

• creating an inventory of PCs and their installed software - Windows, Mac, Linux
• creating an inventory of routers, printers, and anything IP based.
• help desk ticketing
• network monitoring
• nice reporting

Solution 2:

There are lots of solutions (just google "computer inventory"), but the one I know of is OCS Inventory NG, although depending on your needs you may want to look for something a bit more friendly, as this open source project is somewhat complex.
