Monitoring Filemon Regmon Process Explorer TCPView
Filemon/Regmon Watch all file system or Registry accesses in real-time Ideal for troubleshooting broken application installations Useful for developers tracking down bugs or performance tuning file system access Work on all Windows® OSs, including 64 -bit Windows XP Used extensively within Microsoft PSS Windows XP Application Compatibility Microsoft® Office 2000
Using Filemon/Regmon Requires no install or reboot Just start using them Includes filters for including, excluding, and highlighting output Can’t include/exclude filter result codes on Filemon for Win. NT/2 K/XP Requires admin privilege to run Trick: run once as admin and then you can use them as unprivileged users
How Filemon Works Filemon uses a driver to intercept file I/O access A Vx. D on Windows 9 x/Me A “file system filter driver” on Windows NT®/Windows 2000/Windows XP Filemon GUI Application User Mode Kernel Mode Filemon Driver File System Driver
How Regmon Works Regmon uses a driver to intercept Registry operations A “hook” Vx. D on Windows 9 x/Me A system-call intercepting driver on Windows NT/Windows 2000/Windows XP Application Regmon GUI User Mode Kernel Mode Regmon Driver Registry Subsystem
Process Explorer (formerly Handle. Ex) starts where Task Manager ends: See detailed information about running processes, including their paths and command-lines Description of EXE SID from process security token View the DLLs processes have loaded, including version numbers See what handles processes have opened Examine services running within service processes Process Explorer works on all Windows platforms
Common Process Explorer Uses Detect DLL versioning problems Compare the output from a “good” system with that of a “broken” system Use the search feature to determine what process is holding a file or directory open View the state of synchronization objects (mutexes, semaphores, events) Detect handle leaks using refresh difference highlighting
How Process Explorer Works Uses undocumented functions for: Enumerating loaded modules with full path names Enumerating processes and handles Obtains handle names using the aid of a driver Related Tools: Handle – command-line handle viewer Listdlls – command-line DLL viewer
TCPView GUI version of Netstat Works on all Windows platforms Lists active TCP and UDP endpoints Shows endpoint owner on Windows NT/2000/Windows XP/. NET Server Includes auto-refresh and difference highlighting You can close established TCP/IP connections Works using documented and undocumented IPHelper library functions
Other Monitoring Tools Debug. View Monitor application debug output Diskmon Monitor hard disk activity Pmon Monitor process and thread activity Portmon Monitor serial and parallel port traffic Tokenmon Monitor security-related activity

Systems Administration Ps. Tools Ps. List Ps. Kill Ps. Info Ps. Log. List Ps. Service Ps. Exec Ps. Suspend More… Bg. Info Autoruns
Ps. Tools consists of a total of 11 tools They all work on Windows NT/ Windows 2000/Windows XP They all work remotely as well as locally None require manual remote software installation Where’d the “Ps” come from? The UNIX process listing tool is named “ps” The first Ps. Tool was a UNIX “ps”-equivalent, Ps. List
Ps. List View detailed information about running processes Similar to tlist and pulist Default view is mix of CPU and memory information Other views show thread details, memory details, or full information Use the –s switch to run it in a Task Manager-type mode Works using the performance counter API WMI is only available by default on Windows 2000/Windows XP, not on Windows NT 4
Ps. Kill The perfect complement to Ps. List is Ps. Kill Similar to Resource Kit Kill and Remote Kill See a process running on a remote (or local) system with Ps. List, kill it with Ps. Kill Unlike Task Manager, Ps. Kill lets you kill any process if you’re an admin Uses “Debug” privilege Uses auto-installed remote service and Terminate. Process API
Ps. Info Get detailed information about a system OS version: type (pro, server, etc. ) Service Pack Hot-fixes CPU and memory Uptime Volume information Uses documented APIs: Registry (remote, if applicable) WMI for XP product activation query
Ps. Log. List Dump and optionally clear event logs Like eloglist from the Resource Kit Ps. Log. List lets you dump logs using alternate credentials Gets event strings from remote system Like eloglist, dumps in tab-delimited format for easy import into spreadsheets Has extensive support for filtering on record type and date range Uses documented Event Log APIs, which work remotely
Ps. Service Control Win 32® services Like the Resource Kit’s and XP/Server 2003’s SC Unlike SC, doesn’t make you remember and manually specify a “resume handle” Same syntax as SC Omits several esoteric SC options Search the network for active instances of a service Uses documented Service Control Manager APIs, which work remotely
Ps. Exec Remotely execute programs Executes console programs interactively Allows you to start programs as yourself , in alternate user credentials, or in the System account With Ps. Exec you can: Launch a remote command prompt to effect a light-weight telnet Remote-enable “local only” command-line tools like Ip. Config Uses auto-installed remote service
Ps. Exec Options of interest include: -s: Run in System account (instead of account of user running Ps. Exec) -i: Show GUI windows on interactive console -d: Don’t wait for remote process to terminate -c: Copy an executable to the remote system
Ps. Suspend Microsoft provides no process-suspend utility like Ps. Suspend for pausing a process that’s using a resource Memory CPU Network Windows NT and 2000 have no “suspend process” capability, so Ps. Suspend suspends individual threads
Bg. Info (Background Info) If you manage more than a handful of systems, you’ve run into the “what machine is this” syndrome Bg. Info creates an auto-generated informative desktop background System name Memory IP Address OS version Whatever you want!
Autoruns There almost 2 -dozen places that can be used to configure automatically started applications Autoruns shows you all of the locations and displays programs configured to run in them Double-click a folder or key to jump to it in Explorer or Regedit Double-click a configured application to view its properties

File-Related Tools Contig Page. Defrag Streams Strings
Contig Command-line Windows NT/ Windows 2000/Windows XP file defragmenter Useful for: Defragmenting specific files Creating new contiguous files Defragmenting entire disks Uses Windows NT/Windows 2000/Windows XP defragmenting API, documented at Sysinternals
Page. Defragments paging files and Registry hives at boot time Implemented as “native” application: Launched by Session Manager because listed in HKLMSystemCurrent. Control. SetControlSes sion ManagerBoot. Execute value Uses “native” API Uses Contig defragmentation engine Supports command-line options for scripted install
Streams, which require NTFS, used to be rarely used Now there are several components that make use of them: Services for Macintosh Explorer Viruses Streams can search directories for files with streams and display their names
Strings Some executables do not identify themselves with version information or descriptive names Strings will look inside a file image for printable text that include: Registry key and value names Debug strings File names Internal build information
