In Windows Vista this is even a bit more extreme. When you get a UAC prompt for instance, it takes a screenshot of your Default desktop and then displays it dimmed out behind the UAC window in the foreground. The UAC window is part of the Secure Desktop new for Vista and similar to the logon desktop and will not allow you to interact with the Default desktop until you provide input. Other windows stations exist that do not interact with the user. The exceptions to this are services that need to interact with the console user, so these load into Winsta0 instead.
All pages mapped to a specific user use the same memory pages, but each user has their own session space mapped in virtual memory. Session space is divided into four different areas:. As mentioned above, a desktop is an object under which a logical display surface loads. This contains windows, menus and hooks. Session 0 is the base session where services run and is typically also the console session.
In Windows Vista this has been changed to exclusively run services, and the console session is typically Session 1. The diagrams below show the relationships between sessions, windows stations, desktops and services in Windows Vista as compared to earlier operating systems this is from our earlier post on Session 0 Application Compatibility Issues. So now let's dig a little deeper using an example. In the diagram below, we are looking at Session 0 with a user logged in named Bob.
As you can see, Winsta0 contains both processes from the user console session as well as any service that is marked as Interactive. In this case, that includes Winlogon. In this case I have shown Services. As you can see by the connecting bars, it is possible for processes from different virtual sessions to load into a single windows station. The SQL process loads under its own windows station and credentials, so it is not included in either of the other windows stations.
A single desktop object will have a single desktop heap set aside for it. This heap stores various user interface objects, such as the windows, menus and hooks. When an application needs to draw a user interface object, it calls User Works like a charm! Gaby appears to have identified that by default, in XP, Vista, and Win 7, this Terminal Services AllowRemoteRPC registry setting is disabled by being set to 0 probably to prevent you from getting these spammed to you , and if you update this registry key to 1 on any of those above operating systems, the normal msg.
For some reason it doesn't work for me. I changed the value on both computers, then restarted them and it still gives me error 5. I can send a message to the computer I'm on just fine, but I can't send a message to the other one and vice-versa. Both computers are in the same workgroup.
I'm even kind of relieved now, at least I know it's something else and can stop hitting my head against the wall that hard. Could it be an issue with router? I don't know what else could be since it doesn't work on any computer. All computers are in the same workgroup, is there any other requirement? It's also important to follow the syntax exactly for this command. For instance, specify the server, user, and put message in string format in quotes.
So, if you wanted to send a message for peter smith to contact the help desk, for instance, user psmith or whatever the naming scheme is for your domain who is using petersmith-PC the name of his machine the syntax for msg. Change the value data to 1 and then click ok Second, in the start menu search box, type credential manager.
In credential Manager click on add a Windows Credential. The top box wants the name of the remote computer. Third, restart your computer Fourth, you should be ready to send a message. Open a command prompt window. So, you can get back the convenience of the "net send" command, but the receiver must have your credentials entered in to their PC beforehand. This will not be easy to set up in a large office, but the service will not be easily high jacked for unwanted messages.
Do you idiots not think that being able to send broadcast messages might be a useful thing for system admins? You'd use the name the WINS server thinks that it is. In some cases if there's an Active Directory you'd even need to further decorate the workstation name. If the Active Directory name is, say, Contoso then the command would be something like:. This is especially the case if you're on a visitor's laptop and it's not joined the local domain.
In other words, if you're trying to wrap all this in a batch file then appending the computer name with the domain identity is good practice. That said, here's the list of things you'll need to do for each computer that wants to send or receive using MSG. You'd want to run Regedit as administrator and import this file to more easily make the registry modification.
Second, in the start menu search box, type credential manager. I have searched during 3 complete days how to use MSG. EXE command on my home network with 2 PC without success. I was able to push a message out to my windows 7 domain pc's with a modified script I found. You also have to have psexec but it does won't pretty well.

Time-out in seconds - sets the time, in seconds, that the connection will be maintained. The default is 10 seconds. By default, this service is installed when ASP.
NET is installed and is configured for manual start. Change the start behavior to Automatic. Configures IIS to use a SQL Server database to store session state data instead of storing it in the worker process where the application runs. In addition, session state is preserved if either the Windows state service or the web server goes down. Auto Detect - uses cookies if the browser supports cookies; otherwise, no cookies are used.
For desktop browsers that are known to support cookies, ASP. NET tries to use cookies when cookie support is enabled in the browser. When you use the Auto-Detect cookie mode, you should require that expired session IDs be regenerated. Doing this task lets a web server expire and regenerate tokens, which give potential attackers less time to capture a cookie and gain access to Web server content.
Also consider changing the time-out value to less than the minute default. Use Cookies - associates session information with client information for the duration of a user's connection to a website.
