One of my offices has about 23 users. A lot of these users have laptops. When they leave the office with their computer, then come back the next day, they complain they cannot synchronize (offline files) and they can't connect to printers and shares. Upon remoting in, I find that their IP address doesn't jive with DNS, and their connection specific DNS suffix is still their home DNS suffix. I cannot for the life of me figure out how to fix this. Running the four IPCONFIG commands in this order, Release, Flushdns, Renew, Registerdns, fix the issue. But that's not an option as most of these users don't have admin rights and can't run IPConfig. Besides, that's stupid to expect them to have to do so.
