REMOTE COMMAND - Remote Command runs any command remotely and returns the output. It's a good supplement to existing tools that do not run remotely, e.g. "route print", "ipconfig /all", "arp -a", etc. With Remote Command you don't need any client tools on the target machine, and you can even execute a local file on the remote system.

ADVANCED REMOTE INFO - AdvancedRemoteInfo allows you to gather various information about a remote Windows PC on the network. It includes information about hardware, installed software, network configuration, shares and printers, users and much more. You can also interact with the remote machine and terminate processes, start/stop services, send messages and even uninstall software remotely. AdvancedRemoteInfo also offers screenshot capture of the remote desktop, remote shutdown and batch operations to process multiple machines. The information can be exported to Excel , delimited or HTML format. You need administrative privileges on the remote machine to make use of all features.
