To comply with current Internet standards, Internet Explorer (Internet Explorer 5.5, Internet Explorer 5.01, Microsoft Internet Explorer 5.0, Microsoft Internet Explorer 6.0, Windows Internet Explorer 7 for Windows XP, Windows Internet Explorer 7 for Windows Server 2003, Windows Internet Explorer 7 for Windows Server 2003 IA64) limits the number of simultaneous downloads (from the same server) to two downloads, plus one queued download. This configuration is a function of the browser. However, as connection speeds increase, and the number of total connections that are allowed to Internet servers increase, the two-connection limit may be restrictive.

To increase the number of simultaneous connections that are allowed to 15, you can either download and run this REG file or follow these steps:

  1. Start Registry Editor (Regedt32.exe).
  2. Locate the following key in the registry:
    HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings
  3. On the Edit menu, point to New click DWORD Value, and then add the following registry values:

    Value name: MaxConnectionsPer1_0Server
    Value data: 15
    Base: DecimalValue Name: MaxConnectionsPerServer
    Value data: 15
    Base: Decimal

  4. Quit Registry Editor.

With either method, you will need to close all open Internet Explorer windows for the changes to take effect
