If you are purchasing a new computer and having it shipped directly to your office, you will want to follow the New Computer Setup instructions when setting up your computer. Some issues of note:
If your new computer was set up at EIT before being shipped to you, you will want to refer to the File Transfer instructions for copying your documents and archived email to the new computer rather than the New Computer Setup instructions.
Instructions for Net-Regging your machine (a new requirement in the field; we've been net-regging for several years on campus) can be found here (these instructions are also part of the New Computer Setup instructions, however, you can refer to the Net-Reg instructions for more details on what Net-Reg is and why it's used.)
