If you're working with Windows these resources may be of use to you:

Technical Resources

TheElderGeek.com. Windows XP focused site, has forums.
Microsoft-Watch.com. Keep up with the latest MS releases, longhorn etc.
EventID.net. The best way we've found to decipher those incoherent Microsoft Event ID things in the event viewer.
TechNet. You'd think Microsoft's own technet site would be the place to go for MS troubleshooting, but if you're looking for event id resolutions, go to above link, eventid.net
Enterprise Windows News. For network admins mostly. Breaking news on the windows front.
WinSuperSite.com. Don't look for any serious critical thinking here of course...

Windows Forums and Blogs

Anandtech.com OS forums. There's some very good people on these, but watch out for complex solutions to simple problems...
Inside Microsoft. Worth a look.

Readings, Whitepapers

Whitepaper by MS on switching Hotmail from Unix to Windows. Very good read, shows how technically superior Unix was and is for this type of application.
