1. To make your life easier -- When you install NT on the servers, do a parallel install of just the base NT. This way if something happens with your production version, you just boot the parallel version and fix your production one from there. ( To make your life even more easier, you can install this parallel NT on a FAT format - there is a security hole though - Michael)

2. What's the functions of each OSI model layer -- Please Do Not Throw Sausage Pizza Away

The APPLICATION layer provides network services to user applications
                                   This layer offers the user interface and specifies what's being done on the network and how.
                                   Application layer protocols include Telnet, HTTP, FTP, and SMTP.
The PRESENTATION layer provides data representation and code formatting
                                   It extracts data from the application layer and format the data based on various file standards.
                                    This includes JPEG, GIF, MPEG, and ASCII.
The SESSION layer establishes, maintains, and manages sessions between applications
                                   It controls the beginning, middle, and end of individual networking "sessions."
                                    Examples include DECnet, RPC, NFS and SQL.
The TRANSPORT layer segments and reassembles data
                                    It primarily as a gateway between the upper application-oriented layers and the lower network-oriented protocols.
                                    Members of this layer include TCP, UDP, and SPX.
The NETWORK layer determines the best way to move data
                                    This includes such functions as routing and routing protocols.
The DATALINK layer provides physical transmission
                                     In the LAN arena this involves the 802.x IEEE standards.
                                     In the WAN arena this includes HDLC, frame relay, PPP, FDDI, and ATM.
The PHYSICAL layer provides physical link between systems
                                     It defines the physical components that make the network function.
                                    This includes cabling standards and  electrical or light communication methods.
