Running NT Apps on Windows 2000 Server

Microsoft included a Application Compatibility tool called (apcompat.exe). It is available on the Win2K CD-ROM and is part of Win2K's Support Tools. (Located in the CD-ROM's \Support folder, the utility installs when you install the Support Tools.) In some cases, you can use Application Compatibility to fool a legacy application into thinking that the application is compatible with one of several OSs: Win2K; NT 4.0 SP3, SP4, or SP5; or Win9x. The tool also lets you modify behaviors that sometimes cause problems for legacy applications; for example, you can prevent an application from seeing more than 2GB on a disk volume, use a pre-Win2K-style \Temp directory, and disable Win2K's Heap Manager. If a specific application requires a particular set of changes to run, you can make the spoofing behavior permanent so that you don't need to launch Application Compatibility each time you run the application. Finally, you can use one command line to launch a program through the Application Compatibility tool and its various options.
