![]() Source of the corruption is that you forced a handle closed. ![]() Service corrupts its indexes and configuration files, unaware that the Poor technician is assigned the hopeless task of figuring out why the Logging, and the configuration file was overwritten with garbage. The index has been corrupted, the log file has mysteriously stopped Longer the service runs, the more corrupted its indexes become.Įventually, somebody notices the index is returning incorrect results.Īnd when you try to restart the service, it fails because itsĬompany that makes the search index service and they determine that Is closed and the protections against data corruption are lost. ![]() When the original file handle is closed, the mutex handle Meanwhile, another handle you forced closed was reusedĪs a mutex handle, which is used to help prevent data from beingĬorrupted. The logged information goes into the configuration file, Log file handle was closed and the handle reused for its configurationįile. Log some information, so it writes to its log file. The handle for the log file gets recycled as the Operation finally completes, and the search index service finally getsĪround to closing that handle it had open, but it ends up unwittinglyįile, say a configuration file for writing so it can update some Log file in order to record some information, and the handle to theĭeleted file is recycled as the handle to the log file. Gotten stuck temporarily and you want to delete the file, so you Suppose a search index service has a file open for indexing but has By setting the correct permissions in the registry I was able to resolve the issue.Just be very careful with closing handles it's even more dangerous than you'd think, because of handle recycling - if you close the file handle, and the program opens something else, that original file handle you closed may be reused for that "something else." And now guess what happens if the program continues, thinking it is working on the file (whose handle you closed), when in fact that file handle is now pointing to something else. I can see that the IIS worker process cannot access the HKCR\SoftArtisans.FileUp registry key.įrom this example I can see that the w3wp.exe process does not have the correct permissions on the HKCR\SoftArtisans.FileUp registry key. In my case I am searching for Access Denied By clicking on the find icon which appears as binoculars or pressing the shortcut key Ctrl F you can search for a keyword. When reviewing the log you will likely have thousands of entries. In my case it was attempting to upload a file using my FileUp application.Īfter the event has been recreated while Process Monitor is running you can Uncheck capture event and review the log. Once Process Monitor is running make sure that Capture Events is checked. The latest version of Process Monitor is available for download at Process Monitor is an advanced monitoring tool for Windows that shows real-time file system, registry and process/thread activity. In this tutorial I will be troubleshooting a permissions error using Process Monitor (ProcMon). This tutorial is geared towards System Administrators. However these concepts can be applied to most permission issues. SAFileUpSamples/uploadsamples/Simple/asp/formresp.asp, line 27 The specifically error being used for this example is: ![]() The actual permissions needed to resolve permissions issues will vary depending on the desired system configuration. The solution described below is how to troubleshoot the source of a permissions error. You receive some type of permissions error when running your application.
