I've just bought a new MacBook on the last weekend. Now I have configured to use it under Microsoft Environment at my office. Here's the things that I did.
1. Use Directory Service utility to connect to the Active Directory
2. Configure the Entourage to connect to Exchange Server
3. Access to DFSRoot shared drive and created an Alias on the Desktop for fast accessing
4. Connect shared print server. I have no problem connecting to shared HP printers, but cannot find the driver for Fuji Xerox printer.
The Mac can be used under Microsoft environment eventhough its not that smooth, but it's acceptable.
I'm glad I can survive.
