I found this in a few different places around the 'net - hopefully it's helpful:

Set Your Windows So They All Have the Same View

If you like to see lists of your files in a certain way - as large icons, for example, or with detailed information - Windows XP lets you set your view options for all your folders at once the way you want them.

• On the Tools menu in Windows Explorer, click Folder Options.
• Click the View tab.
• Set the view for this folder the way you want it to be for all folders.
• Click Like Current Folder, then click Yes to confirm, and click OK.

Note: To access Windows Explorer, click Start, point to All Programs, and then click Windows Explorer.
