Windows® XP DCOM Config
Information about Windows ® XP DCOM Config.
DCOM is a very little used technology that has been built into the Windows® XP Operating System so as to allow the various software components to inter-operate across any network. With many services and protocols in Windows® XP, Microsoft® appears to have enabled it as ‘always running.’ The Distributed Component Object Model (DCOM) is a protocol that enables software components to communicate directly over a network in a reliable, secure and efficient manner. Previously, it was called Network OLE, DCOM is designed for use across multiple network transports, including Internet protocols such as HTTP. DCOM is based on the Open Software Foundation's DCE-RPC specifications and will work with both Java applets and ActiveX® components through its use of the Component Object Model. Benefit of configuring DCOM on Windows® XP is that DCOM is entered on the network protocol that is available on your computer. Most commonly it runs on top of TCP/IP. They allow the various software components to inter-operate across any network.
Here are some of the issues that can occur while you are configuring the DCOM for your Windows® XP:
- DCOM Registry Corruption Issues
- DCOM Port-Range Configuration Issues
- DCOM Default System-wide Settings and Server -specific Settings Issues
DCOM Registry Corruption Issues
There are times when DCOM registry corruption issues arise that lead to application not running correctly. One known way to end this situation is to write 'bad' data to the registry keys that control the default DCOM security settings. The format of the data is changed in these keys with Windows® XP , so applications which programmatically set the default DCOM permissions properly on a pre-Windows® XP machine can cause DCOM to think it has been disabled when run on a machine with Windows® XP.
DCOM Port-Range Configuration Issues
Sometimes you might notice that World Wide Web Publishing fails to start. If you try to stop services, such as W3SVC, MSFTPSVC, SMTPSVC etc, the attempt fails and an error message comes. The DCOM clients trying to connect with the DCOM server fails. These problems occur due to the improper configuration of the DCOM port range. You can resolve these issues by the following methods. If you do not want to configure DCOM to use a range of ports, delete the registry key, and then restart your computer. You can also configure DCOM on your computer to use a range of ports, by following the path ‘HKEY_LOCAL_MACHINESoftwareMicrosoftRpcInternet registry.’
DCOM provides system-wide settings and defaults along with the server-specific settings. A specific server can use the system-wide default settings or configure their own customized settings. Issues might arise when you try to change the system-wide default settings without knowing whether or not their specific servers are using these settings. So it should be made sure that you provide proper settings for both the aspects.
