Appendix B: Changes to Metabase Properties in IIS 6.0
There are IIS 5.0 metabase properties that are no longer supported in IIS 6.0. When upgrading or migrating from an earlier version of IIS, these properties are still in the metabase, but IIS 6.0 ignores the settings. On a new installation of IIS 6.0, these properties have been removed from the metabase, and they are not available even when IIS 6.0 is running in IIS 5.0 isolation mode.
There is one IIS 5.0 metabase property - CPUResetInterval - that still exists in the IIS 6.0 metabase, but it behaves differently in IIS 6.0.
Table 1.1 lists metabase properties that have changed in IIS 6.0. If your Web sites, applications, or setup programs refer to any of these IIS metabase properties, follow the recommendations described in the table to accommodate these changes and ensure compatibility with IIS 6.0.
