Remarks

The Domain Name Services (DNS) protocol is what applications use to resolve domain names into Internet addresses as well as provide other information about a domain. All of the SocketTools components provide basic domain name resolution functionality, but the Domain Name Services component gives an application direct control over what servers are queried, the amount of time spent waiting for a response and the type of information that is returned.

Requirements

This ActiveX control is supported on Windows 2000, Windows XP, Windows Server 2003, Windows Vista and Windows Server 2008. If you are using Windows 2000, it is required that you have Service Pack (SP4) installed. If you are using Windows XP, it is required that you have at least Service Pack 2 (SP2) installed and it is recommended that you install Internet Explorer 7.0. It is also recommended that all critical updates to the Windows operating system be installed.

The SocketTools Visual Edition components are compatible with any development tool that fully supports COM (Component Object Model) and the ActiveX control specification. This includes Visual Studio 6.0, Visual Studio .NET 2003, Visual Studio 2005 and Visual Studio 2008. If you are using Visual Basic 6.0 or Visual C++ 6.0, it is required that you have Service Pack 6 (SP6) installed. If you are using Visual Studio .NET 2003 or Visual Studio 2005, it is recommended that you install Service Pack 1 (SP1). In all cases, it is recommended that you have the current updates for your development tools installed.

Distribution

When you distribute an application that uses this control, you should install the appropriate file in the Windows system directory. ActiveX controls must be registered on the target system by the installation program before they can be used by an application.
