" Server: Windows Server 2003 and higher (Including IA64). How to find threads in Processes causing high CPU using ProcessExplorer 1. First Launch ProcessExplorer (Microsoft) on the Policy server where High CPU occuring, then fnd the smpolicysrv.exe process – usually run under services.exe Figure 1.1 2. Right click process – select properties. Figure 1.2 Details for the policy server process can be view in each tab Example: TCP/IP - All connection info to the policy server process 3. Click Threads TAB, then sort by CPU Figure 1.3 The graph in figure 1.3 shows Policy Serve process @ 100 %, using Process Explorer we are able to view details of each thread inside the policy server process (CPU each thread is consuming). SiteMinder policy server process 764 contains five threads using ALL CPU 5448, 5904, 3848, 2680, and 4432 Next step is to view thread details, then copy the stack provide to CA Support 4. Click on the high CPU thread, click Stack – copy the stack, then provide to support Figure 1.4 5. To complete the data collection dump the entire process and provide to CA Support a. Right Click smpolicysrc.exe b. Select - Create Dump c. > Select - Create Full Dump Figure 1.5 6. Most useful data to provide CA Support to resolve issue quickest a. List of threads (pic) of all the thread – figure 1.3 b. Copy of thread running high CPU into notepad – figure 1.4 c. Full dump of the policy server process – figure 1.5 d. Policy server SMPS and profile logs – provides log detail on each threads activities .

P 240/1 Process Control on Windows
P240.qxp_June 2018 03/05/2018 22:16 Page 41 Process Control on Windows P 240/1 Optimise and Stabilise Your Windows System by Taking Control of Your Processes Using the information given in this article you will be able to: Investigate exactly what processes are using your PC’s processor and memory, Optimise the performance of your system with perfect process management, Find and close Trojans, viruses and other suspicious processes. You’ve probably come across messages from Windows telling you that an application is no longer responding, and wondered exactly what is happening in the background on your Windows system. The egg timer icon or a little blue circle usually appear, the hard drive grinds away and you wait for what seems like an eternity for Windows to do something. When this happens, it usually indicates that Windows is performing tasks in the background. You can take a look at the list of the processes that are running on your system, but they usually have cryptic names which makes it difficult to work out exactly what is going on. However, if a program or service doesn’t run in a stable way, or you suspect that a virus or Trojan may be doing damage to your system, then you can’t avoid checking which processes are running. In this article I will show you the most important processes that Windows runs internally, and the tasks you need to perform in order to maintain your processes and take control of your system. • Check the Hidden Tasks Your Windows System is Running .................

Process Explorer Copyright © 1996-2012 Mark Russinovich Sysinternals
Process Explorer Copyright © 1996-2012 Mark Russinovich Sysinternals - www.sysinternals.com Process Explorer is an advanced process management utility that picks up where Task Manager leaves off. It will show you detailed information about a process including its icon, command-line, full image path, memory statistics, user account, security attributes, and more. When you zoom in on a particular process you can list the DLLs it has loaded or the operating system resource handles it has open. A search capability enables you to track down a process that has a resource opened, such as a file, directory or Registry key, or to view the list of processes that have a DLL loaded. The Process Explorer display consists of two sub-windows. The top always shows a list of the currently active processes, including the names of their owning accounts, whereas the information displayed in the bottom window, which you can close, depends on the mode that Process Explorer is in: if it is in handle mode you will see the handles that the process selected in the top window has opened; if Process Explorer is in DLL mode you will see the DLLs and memory-mapped files that the process has loaded. Process Explorer also has a powerful search capability that will quickly show you which processes have particular handles opened or DLLs loaded. The unique capabilities of Process Explorer make it useful for tracking down DLL-version problems or handle leaks, and provide insight into the way Windows and applications work. You can obtain equivalent command-line tools, Handle and ListDLLs, at the Sysinternals Web site.

The Svchost.Exe Process

The versions of the libraries used in the tutorial are: termdd.sys version 6.1.7601.17514 rdpwsx.dll version 6.1.7601.17828 rdpwd.sys version 6.1.7601.17830 icaapi.dll version 6.1.7600.16385 rdpcorekmts.dll version 6.1.7601.17828 The Svchost.exe process In the Windows NT operating system family, svchost.exe ('Service Host) is a system process that serves or hosts multiple Windows services. It runs on multiple instances, each hosting one or more services. It's indispensable in the execution of so- called shared services processes, where a grouping of services can share processes in order to reduce the use of system resources. The tasklist /svc command on a console with administrator permission shows us the dierent svchost processes and their associated services. Also in PROCESS EXPLORER you can easily identify which of the SVChosts is the one that handles RDP connections.(Remote Desktop Services) https://www.coresecurity.com/node/63548 1/61 13/08/2019 Low-level Reversing of BLUEKEEP vulnerability (CVE-2019-0708) | Core Security STEP 1) Initial reversing to nd the point where the program starts to parse my data decrypted The rst thing we'll do is try to see where the driver is called from, for that, once we're debugging the remote kernel with Windbg or IDA, we put a breakpoint in the driver dispatch i.e.
