Windows Built in Computer Repair Tools

Windows Support tools (these are located on the windows CD in the directory SUPPORTTOOLS, run the setup program to install them,



most of these run directly from the CMD or command line screen screen, to get to this go to the start menu and select run type CMD

I've added the Microsoft brief description to all the tools

Netcap.exe (Network Monitor Capture Utility) This command-line tool allows a system administrator to monitor packets on a LAN and write the information to a log file. NetCap uses the Network Monitor Driver to sniff packets on the local segment that fit its filter criteria.

Netdiag.exe (Network Connectivity Tester) This command-line diagnostic tool helps to isolate networking and connectivity problems, by performing a series of tests to determine the state of your network client, and whether it is functional.

These tests, and the key network status information they expose, give network administrators and support personnel a more direct means of identifying and isolating network problems.

Moreover, because this tool does not require that parameters or switches be specified, support personnel and network administrators can focus on analyzing the output, rather than on training users how to use the tool.

Netdom.exe (Windows Domain Manager) This tool enables administrators to manage Windows 2000 domains and trust relationships from the command line.

Nltest.exe This command-line tool helps perform network administrative tasks. You can use NLTest to:

(You can easily resolve soft page faults with Virtual Memory Manager.) A sustained high rate of hard page faults might indicate a shortage of memory and can cause a disk bottleneck.

Use PFMon to trace the source and number of page faults in a process and display the data in the command window, write it to a log file, or both.

Pmon.exe (Process Resource Monitor) This command-line performance tool displays several measures of the processor and memory use of processes running on the system.

The PMon display appears in the command window. It is updated automatically every few seconds and requires no configuration.
