This article is written for Microsoft Windows XP. However, the "Manual updates to your computer clock" section applies to all versions of the Microsoft Windows operating system.

If your computer is a member of a domain, your computer clock is probably synchronized automatically by a network time server. If your computer is not a member of a domain, your computer clock is automatically and regularly synchronized by an Internet time server.

ShowHow can I tell if my computer is part of a domain?

  1. Click Start, right-click My Computer, and then click Properties.
  2. Click the Computer Name tab.

System Properties dialog box

This tab lists several settings, including whether your computer is a member of a domain or workgroup. Whichever one your computer is a member of, the name is also displayed.

  • The Update Now button is not available unless the Automatically synchronize with an Internet time server check box is selected.
