Systems Management content from Windows IT Pro Ps. Exec is a command- line tool that lets you execute processes on remote systems and redirect console applications' output to the local system so that these applications appear to be running locally. You can download Ps. Exec for free from the Sysinternals website. Here are some advanced tips and tricks to help you leverage the full potential of Ps. Exec as a systems management utility. Related: Ps. Exec, User Account control and Security Boundaries The Ps. Tools Suite Ps. Exec is a member of Sysinternals' Ps. Tools suite, which contains 1. ![]() To be in the suite, tools must conform to a set of specifications that includes supporting Windows NT 4. Ps. Tools utilities require no manual installation of software on the remote system, and they let you specify alternative credentials to access the remote system. I named the tool after the ps utility that performs the same function on UNIX systems. ![]() ![]() Related: Ps. Exec to the Rescue As with many of the tools in the Ps. Tools suite, Ps. Exec's ability to run processes remotely requires that both the local and remote computers have file and print sharing (i. Workstation and Server services) enabled and that the default Admin$ share (a hidden share that maps to the \windows directory) is defined on the remote system. The reasons for these requirements will become clear later when I describe how Ps. Exec works. However, if Ps. Exec were only able to launch a program on a remote system, its usefulness would be limited. Ps. Exec's ability to redirect the input and output of console applications is what makes the tool a versatile systems management utility. Figure 1 shows Ps. Exec's command- line options and gives a hint as to its capabilities. Many Windows administrative console tools can run only on a local machine. ![]() ![]() ![]() Ps. Exec lets you remote- enable any of them. For example, Ps. Exec lets Ipconfig, the Windows utility that displays the TCP/IP configuration for a system's network adapters, show a remote system's configuration. A sample command for that use is psexec \\remote ipconfig where remote is the name or IP address of the system you want to query. You'll see Ipconfig's output as if you had run Ipconfig on the local machine. ![]()
Command to reset, flush or clear your DNS cache. Vista, Windows 7, and WIndows 8 These same directions work in versions of Windows after XP; however, you’ll need to. Frequently web connection problems can be traced to a corrupted DNS cache. Flushing this cache is an easy fix to many of these problems. This is how to flush the.

If you know that the program isn't in that directory, enter its full path on the remote system; if it's an executable on the local system that you want to execute on the remote system, specify the - c switch and the file's local path. The - c switch directs Ps. Exec to copy the specified executable to the remote system for execution and delete the executable from the remote system when the program has finished running. This use of Ps. Exec is similar to running a Telnet client on the local machine and connecting to a Telnet service on the remote machine, but you don't need to have the Telnet service, or any other special service, running on the remote system. Simply execute the command: psexec \\remote cmd If you want to execute one console command on the remote system, pass the command prompt the /c switch followed by the command you want to execute. For example, the command psexec \\remote cmd /c ver displays the Windows version number of the remote system on the local machine's console. To make this task even easier, Ps. Exec takes multiple computer names, the name of a text file containing a list of computer names, or the special name of \\* that results in an enumeration of all the computers in the current domain. For instance, to execute the Microsoft My. Doom removal tool on computers named Remote and Remote. Upon exit, a process specifies an integer that the process's parent process can read. Programs often use the exit code to report the success or failure of their execution. Whenever a process executed with Ps. Exec is completed, Ps. Exec displays the process's exit code and returns the exit code as its own exit code. You should test a program's behavior or check its documentation to determine what that program's specific error codes mean, but an exit code of 0 typically means success. The - s switch specifies that Ps. Exec should execute the command under the System account. I'll discuss this option more in a moment. By default, the process you execute on the remote system impersonates the account from which you run Ps. Exec on the local system. Impersonation is somewhat restricted from the perspective of security—the remote process doesn't have access to any network resources, even those that your account typically would be able to access. If the account in which you're running doesn't have local administrative privileges on the remote system, the process you want to run requires access to network resources, or you want to run a process in a different account, then use Ps. Exec's - u switch to provide an alternative account name. For example, you could enter the command psexec \\remote - u remote\administrator - p adminpass ipconfig to run Ipconfig under the Administrator account on the remote machine. Use the - p switch to enter the password for the account you specified with the - u switch. If you omit the - p switch, Ps. Exec prompts you to enter the password (for security reasons, Ps. Exec doesn't echo the password you enter to the screen). To run in a different account, Ps. Exec must use that account to log on to the remote system. Ps. Exec therefore requires the password on the remote system and sends the password in clear text from the local system. You need to be aware of this fact if unauthorized network sniffers could intercept traffic between the local and remote system. The System account has powerful privileges. Some file- system and registry resources have default security settings that permit access only from the System account—examples are the HKEY. The command is this: psexec - s - i c: \windows\regedit. Note that the command doesn't include a remote computer name and does include the - i (interactive) switch. When you enter the command, regedit will appear on your desktop running in the System account, and you'll be able to look inside the HKEY. The - i switch is what causes regedit to appear on the console desktop, and it's typically useful only when you want to run a GUI application on the local system where you can interact with it. Several viruses use Ps. Exec to propagate within a network, and as a result, several major antivirus products flag Ps. Exec as a Trojan horse program or a worm. Remember that Ps. Exec works on remote systems only if it runs within an account that has administrator group membership on the remote system. In other words, unless the account from which you run it has administrative access to a remote system, Ps. Exec won't be able to execute a process on the remote system. In addition, Ps. Exec's functionality can be achieved in other ways; thus, Ps. Exec is only a convenience for virus writers, who could otherwise easily implement the functionality that Ps. Exec provides. Ps. Exec does so by extracting from its executable image an embedded Windows service named Psexesvc and copying it to the Admin$ share of the remote system. Ps. Exec then uses the Windows Service Control Manager API, which has a remote interface, to start the Psexesvc service on the remote system. If you specify the - d (don't wait) switch, the service exits after starting the executable; otherwise, the service waits for the executable to terminate, then sends the exit code back to Ps. Exec for it to print on the local console. What is Wireless Network. Custom Search. Wireless network is a network set up by using radio signal frequency to communicate among computers and other network devices. Sometimes it’s also referred to as Wi. Fi network or WLAN. This network is getting popular nowadays due to easy to setup feature and no cabling involved. You can connect computers anywhere in your home without the need for wires. When the computer send out the data, the binary data will be encoded to radio frequency and transmitted via wireless router. The receiving computer will then decode the signal back to binary data. If you heard about wireless hotspot, that means that location is equipped with wireless devices for you and others to join the network. You then set up wireless client by adding wireless card to each computer and form a simple wireless network. You can also cable connect computer directly to router if there are switch ports available. The coverage provided is generally referred to as the coverage cell. Large areas usually require more than one access point in order to have adequate coverage. You can also add access point to your existing wireless router to improve coverage. The 2 examples which I specified above operate in this mode. An ad hoc network consists of up to 9 wireless clients, which send their data directly to each other.
