Apparently, Word's enumerating the printers upon startup caused this DLL to load, which in turn caused the process to die why this was happened I don't know-perhaps the user had installed a bogus version; but since the system no longer had a printer it really didn't matter. In another example, the Regmon saved a user from doing a complete reinstall of his Windows XP desktop system. The symptom was that Internet Explorer IE would hang on startup if the user did not first manually dial the internet connection.
This internet connection was set as the default connection for the system, so starting IE should have caused an automatic dialup to the internet because IE was set to display a default home page upon startup. Following my new motto, I ran Filemon and Regmon and looked backwards from the point in the log where IE hung. Since the dialup connection's name was not "ATT", I suspected this was left over registry junk from the uninstall that was causing IE to choke.
So, I renamed the key and the problem went away! Using the "compare the logs" technique helped solve why Access was hanging on a programmer's XP workstation trying to import an Excel file. Importing the same file worked fine on other users' workstations, but failed on this one workstation. So, a capture was made of Access on the working and failing system. After appropriately massaging the log files they were compared with Windiff.
The first several differences were due to names of temporary files being different and due to some filenames being different due to case differences, but of course these were not "relevant differences" between the two systems. So, the user renamed that DLL to. One class of problems Filemon is incredibly useful for is uncovering file permission issues. Many applications do a poor job of reporting access denied errors. However, running Filemon reveals clearly failures of this type since the result column shows "ACCESS DENIED" for failures to open files due to rights issues and the most recent version even shows the username that failed to access the file.
Two specific examples where this was the case:. These are just a few examples-I have many other success stories where Filemon and Regmon and Process Explorer, which I didn't discuss here have saved the day. Filemon, one of the utilities David highlights in his editorial, has undergone its first major revision in several years. The new release brings a new level of usability to a tool that already had an accessible user interface. The most significant enhancement is the change to how file system activity is presented in Filemon's default setting when run on Windows NT, , XP or Server , something I'd been thinking about for a while and that I finally implemented based on real user feedback from David.
There are numerous other examples of operations that most would classify as "noise" and operation names that aren't self-explanatory. Filemon version 5. In addition, the default view omits file system activity in the System process, which is the process from which the Memory and Cache Manager's perform background activity, and all Memory Manager paging activity, including that to the system's paging file. The Options Advanced menu item will satisfy users, such as file system filter driver developers, that want the "raw" view of file system activity shown by previous Filemon versions.
Several users, including Microsoft employees, requested that Filemon show the account in which "access denied" errors occur in order to aid security-settings debugging in Terminal Services environments. In response version 5. Many troubleshooting sessions focus on identifying the files a process accesses or attempts to access, in which case operations like reads, writes and closes are just noise. In recognition of this fact I've added a new "log opens" filtering option enables you to isolate just open operations.
Another major change is in the way Filemon v5. In previous versions each mapping shows up as a drive letter in the Drives menu. Now, all such mappings are encompassed in the "Network" selection of the Volumes menu which is the renamed Drives menu. This change makes it possible for you to view network file activity even when you don't have a mapped network share, as was required by previous Filemon versions.
There are numerous other minor changes to the latest Filemon, including an updated menu structure that mirrors the more usable menus I introduced in Regmon several months ago. Developers of software, hardware, and networking products support Sysinternals by purchasing licenses to redistribute our code. However, during the past year we've found a range of software, from Trojans to commercial products from some multi-billion dollar corporations, containing unlicensed Sysinternals source code.
In an effort to keep Sysinternals growing and our products legally licensed we've discontinued publishing the source code for some of our products, including the latest Filemon and Regmon releases. We will continue to make source code available to commercial licensees. If you discover mirrors for Sysinternals source code please let us know.
DebugView is a very popular Sysinternals utility that software developers use to capture debug output generated by their software. Version v4. A Microsoft-requested option allows you to capture debug output of processes executing within the console session of a Terminal Services environment when you run DebugView in a non-console session. Several users requested more and longer filters, filtering on process IDs, and the ability to insert comments into the output, all of which are possible with the latest version.
The new release is rounded out with several bug fixes, better support for extracting kernel-debug output from crash dump files, and better balloon windows for text that exceeds the width of its output column and even the screen. The SID Security ID duplication problem is one that you'll encounter if you use a preinstall Windows image to deploy more than one system. Each computer that shares the image has the same internal Windows SID, which is an identifier that the Windows security subsystem uses as the basis for local group and account identifiers.
Because of the security issues the sharing can cause most administrators take steps to post-apply a unique SID to each computer using a SID changing tool.
Version 4. A feature requested by many administrators is NewSIDs ability to apply a SID that you specify, something that might be useful for migrating an installation's settings to a different computer or for reinstalling. As NewSID runs it causes the Registry to grow when it applies temporary security settings to portions of the Registry in order to make them accessible.
This bloating can cause the Registry to exceed its size quota so a new v4. Prior to v2. For example, you can shutdown and power-off if a system supports power management, lock the desktop, and logoff the interactive user, all on the local or a remote machine, without manually installing any client software.
Download PsShutdown v2. We've all been annoyed by the installation of unwanted applets that run when we log in and been frustrated in our search for their startup command. It's no wonder when Windows has close to 2-dozen mechanisms for such activation. In some cases you might uncover undocumented parameters, especially for third-party drivers and services.
After you pass the point in the log where boot and system driver initialization is complete you'll begin to see records created by the smss. Session Manager is the first user-mode process launched during a boot.
Next you'll see it determine what DOS device mappings it should create e. Session Manager typically launches Chkdsk autocheck. Both of these generate interleaved Registry accesses as they start up concurrently. Winlogon can be seen querying the. Default key's contents are user preferences that are active when no one is logged in, and Winlogon uses them for the screen on which it displays the logon dialog box. To see where Winlogon determines where to load your user profile from as you login search for "Profilelist".
A particularly interesting part of a log is where the Service Control Manager services. This is the point when the boot is considered successful - up to that point any boot failures due to a mis-configured control set might be avoided by choosing "last known good" during a reboot.
Contrary to some articles on the Registry the "last known good" copy of the Registry only contains the control set, and not the entire Registry - this is confirmed by a Regmon log. If you have Explorer as your shell you can examine the Registry accesses it performs as it starts up when you log in. The system tray process, systray. A trace that goes through shutdown will show that the last Registry activity performed is by Winlogon, which performs relatively few operations while closing down.
