Windows Process Description:

The catsrv.dll file is used by the COM+ Configuration Catalog Server to provide a comprehensive searching service for Intranet, Extranet or Internet. It acts as a single point of access that allows users to search for information across a network. This Catalog Server is fundamentally used as data storage that holds the COM+ Configuration data.

COM+ is an extension of Microsoft's strategic building block approach for developing program applications. It provides new runtime services and it is a newer set of operating system services added to COM for application components while running. With COM+, it is easier to build COM components and to deploy and build COM based applications. COM+ enables the extensive interoperability between components regardless of their implementation.

The COM+ Configuration Catalog presents the COM+ data in a hierarchical way. Furthermore, this catalog provides the means by which the COM+ Class Registration Database or RegDB can be accessed. When there are configured components installed in the COM+ applications, the RegDB database holds those data configuration. The RegDB stored data are, then, used by the COM+ runtime for proper activation of the objects in an appropriate context and for determining what kind of services are to be provided according to its declarative elements.

The catsrv.dll file occupies 229,376 bytes of disk space on Windows XP. When a user needs to repair install his XP operating system, a COM+ setup error might occur where the catsrv.dll file fails to load in the library C:/ Windows/ system32. In order to resolve this, the CMD.EXE window needs to be opened and type the commands regsrv32 /s ole32.dll and regsrv32 /s oleaut32.dll. Then, proceed to the Add/Remove Windows Component of the Add/Remove Programs in the Control Panel and press next and reinstall COM+.
