isolation mode and others in IIS 5.0 isolation mode. If applications require separate modes, the

applications must run on separate servers.

Compatibility Issues

After you perform an upgrade of the operating system, IIS is configured to run in IIS 5.0 isolation

mode by default. Before configuring IIS 6.0 to run in worker process isolation mode, you should

evaluate whether your Web sites and applications are compatible with worker process isolation

mode. Most of the compatibility issues with IIS 6.0 occur when configuring IIS 6.0 to run in worker

process isolation mode.

One of the most common reasons for incompatibility with worker process isolation mode is that

applications do not recognize custom ISAPI extensions or DLLs that depend on the memory and

request processing models used by earlier versions of IIS. Determine application compatibility in

your lab before upgrading your existing IIS server, and if you determine that your applications are

not compatible with worker process isolation mode, you can run the applications in IIS 5.0

isolation mode.

ASP.NET 1.0: Previously installed and dependent on

Need for most secure model, application recycling

abilities, and new features of IIS 6.0

Enabling IIS 6.0 After an Upgrade

For security reasons, the WWW Publishing service is disabled when you upgrade from Windows

2000 Server or Windows 2000 Advanced Server to Windows Server 2003 or Windows

Server 2003, Enterprise Edition, respectively. In a Windows 2000 Server installation, IIS 5.0 is

installed by default, and in many cases the WWW service was not used. As a result, the WWW

service is now disabled after an upgrade.

IIS is not disabled by upgrade.

IIS is disabled by default
