A useful Solaris shell script to determine the properties of your network cards:
#!/bin/sh
# Only the root user can run the ndd commands
if [ "`/usr/bin/id | /usr/bin/cut -c1-5`" != "uid=0" ] ; then
echo "You must be the root user to run `basename $0`."
exit 1
fi

 Group policies make it easier to centrally distribute Windows XP Service Pack 2 from Windows 2000 Server or Windows Server 2003, but Windows NT servers don't offer group policies. Instead, NT administrators can distribute Windows XP SP2 using logon scripts.
You can install Windows XP service packs through logon scripts as easily as you can execute other workstation configuration settings. If you don't use logon scripts on your server, you'll have a little bit of extra work because you'll need to create the initial logon scripts and then add them to every user in User Manager For Domains--or at least those to which you want to deploy SP 2.

If you support a Windows XP system that occasionally has problems booting up, you may want to install the Recovery Console on that system. Once you install the Recovery Console, it will always be available when you need to troubleshoot the boot process. This will save you from having to search for a Windows XP installation CD every time you want to run the Recovery Console.
Here's how to add the Recovery Console to an XP machine:

Here are some very useful sed one liners, mostly stolen from somewhere.... enjoy!
FILE SPACING:
# double space a file
sed G
# triple space a file
sed 'G;G'
# undo double-spacing (assumes even-numbered lines are always blank)
sed 'n;d'

We've developed a batch file that can save you some time by automatically running Chkdsk and Defrag on your Windows XP machines. First, it does a read-only Chkdsk. If Chkdsk sets the errorlevel to 3, meaning that it found errors and needs to be run with the /F (fix) option, the file checks to see whether the systemroot or pagefile exist on the drive. If so, it runs Chkdsk the next time the system is rebooted. If systemroot or pagefile don't exist on the drive, it runs a Chkdsk /F /R now, and then it runs a Defrag -b and a regular Defrag. (The -b switch is an undocumented switch that optimizes the drive for boot.)

When you install Windows XP, the installation procedure prompts you to enter your user name and a company name. Then, this information displays on the General tab of the System Properties dialog box under the Registered To heading. Unfortunately, Windows XP doesn't provide you with a tool for changing this registration information. However, you can alter the registration information by editing the registry. Follow these seven steps to alter the information:

The nice command lets you run a command at a priority lower than the command's normal priority. The nice value can range from 0 to 39, with 39 being the lowest priority. For example, if a command normally runs at a priority of 20, specifying an increment of 5 runs the command at a lower priority, 25, and the command runs slower.
A standard user usually has a nice level of 20 so you are able to reduce the nice level of a user from 20 to 39 (0 to -19). Edit the /etc/passwd file entry for the user, and run the users shell program at a lower nice level.

Assuming you already have grub installed on your system and /boot is part of your root filesystem you would use the following steps to configure yoursystem to boot using grub.

Set the root partition (first disk, first partition):
grub> root (hd0,0)
Install the boot record on the MBR:
