Microsoft Outlook 98 and 2000 provide the capability for you to share your calendar, contact lists, and other folders with others using Outlook. This can be very helpful for small offices that don't want to purchase Exchange Server or Micorosoft's Small Business Server 2003 software. I've provided some basic instructions for how to use Microsoft Outlook's Net Folders feature to do so.
Keep in mind that address is not necessarily the IP address assigned to your computer if you are on a Local Area Network (LAN). If you are behind a firewall or a router performing Network Address Translation (NAT), your locally assigned address may differ from the address websites and other servers on the Internet see as your originating address. If your router is performing NAT, there may be multiple computers behind the router with unique IP addresses, but the router may have ony one outside IP address. The router keeps track of which connections are associated with which inside IP addresses.
You can determine your system's actual address by going to What is my IP Address?. Or if you are using a PC running Windows by getting a command prompt by clicking on Start, Run, and then typing command and hitting enter. Then type ipconfig, which will show you your IP address, your subnet mask, and the default gateway address, which is the address of the system, e.g. a router, that your system would use to gain access to the Internet. On a Linux system, if you are logged on as root, you can type ifconfig -a, then look for the "inet addr" value, which will usually be associated with the eth0 interface. The l0 interface is a "loopback" address of 127.0.0.1, which is just an address that allows a system to communicate with itself.
If you run the mailq command and see an "Out of memory" error as in the following example, then the recipient's email server is experiencing a memory problem.

I've found Norton Ghost to be very useful for backing up systems. The program will allow you to back up an exact image of a drive or partition. It will work with FAT, FAT32, NTFS, ext2, and some versions will even allow you to backup ext3 partitions.
A problem I've encountered is that the program only allows you to generate bootable diskettes. Some newer sysems don't have a floppy drive. A boot CD is needed for those systems. For those systems, generate a bootable floppy diskette of the type you want, e.g. with USB and Firewire support or for a network backup. Then use a CD writing program to generate a bootable CD. Many newer CD burning programs allow you to generate bootable CDs from a bootable floppy.
The procedure I've listed below is for Roxio's Easy CD and DVD Creator 6, but you should be able to use a similar procedure with another program, e.g. Nero.
If the system isn't configured to try booting from a bootable CD before attempting to boot from the hard disk, you will need to enter the BIOS setup routine, which you can do after you power the system on, by hitting the appropriate key, e.g. Del (Dell) or F1 (Gateway). Or many newer systems will allow you to hit a key at startup time to specify what device you want to boot from, e.g. F12 (Dell) or F10 (Gateway).
