[Tatsuya Deals]

SummaryThe fltMgr.sys is a critical system file that manages data storage drives and helps Windows interact with the storage drives. However, if the fltMgr.sys has failed, it will crash the computer, show a BSoD screen, and make the PC unbootable. If you have recently encountered this error, here are some methods you can try to resolve it. Unbootable computers can stop you from accessing data on the storage drives. In such a case, you can use professional data recovery software to retrieve your files.

BSoD or Blue screen of death errors are the most dreaded errors in Windows. They indicate a major issue and unexpectedly crash computers. One such BSoD is the fltMgr.sys blue screen of death, which occurs due to multiple reasons like virus infection, corrupted data, and more.

The fltMgr.sys or Microsoft File system Filter Manager file is an important part of the OS, which handles data storage drives like hard drives. Windows uses this file to interact with the system storage and file manager. This file also ensures that the hard drives are accessible and their data readable.

To fix the fltMgr.sys BSoD error, we will first use System Restore to restore the PC to a previous healthy state. While this has helped a lot of users, it might not work every time. In such a scenario, we will reinstall Windows, which is the last resort to fix any Windows error.

Get hold of a professional data recovery software like Stellar Data Recovery Professional to recover your data stuck in an inaccessible system. Simply create a bootable recovery media (USB) using another PC and boot into the problematic PC. Refer to our guide to perform data recovery from an unbootable PC.

For booting your computer via installation media, you will have to change the boot sequence by going into the BIOS. Once it is done, your computer will restart automatically and display the installation screen. Follow the instructions on screen to proceed with the OS installation procedure. You can also refer to this guide for detailed steps.

Like any other BSoD error, the fltmgr.sys blue screen error can unexpectedly crash the computer and make it unstable. We hope one of the methods explained above helped you quickly resolve the blue screen error.

I have a third party application running on Windows Server 2003 SP2 that is getting an "Insufficient Server Resources" error. It just started exhibiting this behavior for no apparent reason. I ran ProcMon to see where it is happening. In each case, it happens to be reading a file on another file server. ProcMon shows the name of the file and the error "Insufficient Server Resources" at the same time as the application pops up it's own error message box that says essentially the same thing.

The ProcMon stack trace seems to indicate that the error emanates from fltmgr.sys (the Microsoft File System Filter Manager). The stack trace also contains calls into rdbss.sys and ntkrnlpa.exe. Neither the system event log nor the application event log show any errors.

Additional Info: The other server (the file server) is also Windows 2003 SP2. The third party application is Concordance -- which I'm automating via COM. One critical point that I left out is that the application runs fine accessing this and other files on this server for a period and then generates this error. If I dismiss the dialog box, the driving application can continue to invoke Concordance (which in turn reads these files) for a while and the pattern repeats. It runs for a while and bombs out with the insufficient server resource error. But once I dismiss the dialog, it is as if the server no longer has a problem until, of course, it recurs. I've monitored memory and handles with Process Explorer during the period before the error pops up and nothing obvious is being depleted.

The only thing that springs to mind that might be a generic issue rather than one specific to ThirdPartyApplication(tm) is that if the machine it is reading the file from does not have sufficient client access licenses. With server editions it depends how you have the licensing configured and what licenses you have (for XP there is a fixed limit of 10 concurrent connections if I remember rightly). I have seen connections get "hung" in some cases on XP, such that no new file sharing connections can be opened until XP is restarted, though I have never seen this on a server edition, so the old faithful solution of restarting Windows may be a quick-fix work-around until you can find a more permanent solution.

If it isn't a licensing issue then you should probably contact the creators of that third party application as your first resort: they may be aware of a possible issue and already know how to fix or work around it.

ps. for questions such as this, it is helpful to specify the exact Windows version+variant that is installed on both machines, and what the third party application in question actually is - then if by chance someone else has hit the exact same problem previously you might get a quicker (more accurate) answer.

Is there an error code (0x0000000) logged in the event viewer or provided in the error box? I've ran across this problem a few times before, first was caused by an older version of Symantec enterprise (like 9.0) and the second time it was due to bad ram.

Security permission issues (app unable to access the file)

Server 2003 getting in the way and blocking files from an untrusted server, usually occurs with remote executed exe files though

Antivirus autoprotect scanning the file while the app is trying to open it causing an i/o lock

simply bad error handling in the application

The fitmgr.sys failed bluescreen error can appear on your computer due to various factors. A common problem that may be responsible for the error is outdated or corrupt drivers. When the relevant driver for the fltmgr.sys process is outdated, it can result in BSoD.

Issue: Hi, I recently upgraded from Windows 8 to Windows 10, and all went well at the start. However, lately, I have been getting a blue screen error SYSTEM_SERVICE_EXCEPTION (fltmgr.sys). As soon as the computer restarts, it works fine, but the problem is recurring. That is why I am looking for help. Is there anything I can do to stop these errors?
