How to display 32-bit dcom component configuration in 64-bit windows, 32-bit dcom In the running column, enter the command dcomcnfg to open the Component Service Management window, but the Microsoft Excel program cannot be found. This is mainly a 64-bit system problem. excel is a 32-bit component, therefore, it cannot be seen in normal system component services. You can enter comexp. msc-32 in the run box t

DCOM Overview Microsoft's Distributed COM (DCOM) extends the Component Object Model Technology (COM) to support communication between objects on different computers on the LAN, Wan, or even the Internet. With DCOM, your applications can be distributed in a location to meet the needs of your customers and applications. Because

Bandwidth and potential problems Distributed applications use the advantages of the network to combine components. Theoretically, DCOM hides the fact that components run on different machines. In fact, the application must take into account the two main limitations of network connection: Bandwidth: The size of parameters passed to the method call directly affects the time when the method call is completed. There is a problem: physical distance and

com has launched a general attack code for unpatched Win2000/WinXP attacks, therefore, this vulnerability is more likely to be exploited to become a worm that can infect Win2000/WinXP machines with the rpc dcom vulnerability. Such as the Exploit for Win2000 and WinXP published on PacketStorm: /* Windows 2003 * Coded by.: [oc192.us]:. Security** Features:**-D destination host to attack.**-P for port selection as exploit works on ports other than 135 (

system. At the same time, this vulnerability could be exploited remotely by attackers, Arbitrary code can be executed remotely on a machine that does not fix the vulnerability, causing the attacker to have complete control over the vulnerable machine. The assumption of the five RPC DCOM worms 1. The vulnerability is more likely to be exploited as a worm capable of infecting win2000/winxp machines that have RPC

1. DCOM The process transparency of COM is manifested in the Component object and client program can have their own process space, can also share the same process space, COM is responsible for the customer's call to the Component object correctly, and ensure the correctness of the parameters passed. Component objects and client code do not need to consider the details of the invocation delivery, as long as the normal function calls are implemented in

First, COM/DCOM is the component/Distributed Component Model standard, and CORBA is the service standard of distributed applications. For distributed applications Program Create services and service objects to execute services called by the client. Soap is a communication protocol for Distributed Objects Based on XML and HTTP, and a protocol for communication between COM/DCOM and CORBA objects. In fact, th

In fact, this method is inherently unscientific. DCOM itself is a form of COM, but since we hear that com generally treats it as a locally executed COM, DCOM, of course, is the Distributed COM, which is executed on another computer on the network. the Difference and connection between COM and DCOM were born. Differences: COM has two forms: Dynamic Connection Li

There are two types of configuration: client configuration and Server Configuration: First: client Configuration 1. Run the server on the client. The system automatically registers the server. Then, click "start"-> "run" and enter "dcomcnfg". Then press enter to start the DCOM configuration.2. on the general page, double-click your application server to open your application server DCOM attribute settin

By using ATL, you can easily create DLL (in-process components) EXE and service (out-of-process components)I think this is easy to handle. It is also easy to insert simple COM objects into the project, but there is a small problem:When creating DCOM, you need a DLL that generates a proxy/stub. This is a problem. The procedure I have tried is to output the file to be created in the directory through the vc6 project.A makefile with the extension of. mk.

unauthorized access, to manage password changes, and to handle the danger of passing passwords on the network. Therefore, the distributed platform must provide a security framework to differentiate users in different regions or users in different groups so that the system or application can know who will operate a certain component. DCOM uses the extended security framework provided by Windows NT. Windows NT provides a solid set of built-in security

Local connections can use the DCOM proxy, but essentially DCOM Proxy is used AO Object and ArcGIS Server Server objects. Therefore, for local connection, the client must have an AO object. Of course, you can also directly use the ao api (which can be considered as the AO proxy of the Remote Server Object) without using the DCOM proxy, (But using

In general,. Net EXE assemly will have a corresponding *. EXE. config configuration file. When you need to read configuration information, you can directly read the key values in *. EXE. config through configurationmanager. etettings [Index], but there are few situations where DLL Assembly requires config file. If the current DLL Assembly name is test. dll, if you call configurationmanager in test. DLL to read test. dll. config, it will fail! Of course, it is rare to read *. dll. config from DLL

Application techniques for invoking DCOM components in ASP 1. Write DCOM components: Suppose we want to remotely start the DNS service through an ASP page, and the DNS server is not the same machine as the Web server. We can write an ActiveX DLL to implement this functionality. First we set up a batch file Startdns.bat, written in the file: Net Start DNS. Save the file in a directory of the DNS server, such

For IIS server, you must first install the Excel Development Kit and. Net programmable support.
