BSOD Caused By Tcpip.sys Stop 0xD1

» I've been wrestling with a recently bought Dell XPS laptop which began crashing with BSODs after a month or so. A month later, and I'm still struggling with it. The crashes are less common now, after I reinstalled Windows 7 from scratch, but it still throws its toys out of the pram every few hours.

» Tcpip.sys error is an executable application error that is closely related to Tcpip.sys file. Tcpip.sys error can be caused by malware & spyware infections(Worm:Win32/Autorun.AAF), out-of-date or corrupt drivers, obsolete registry entries, horrible registry errors and incorrect version of Tcpip.sys file.

In a typical Windows install software adds entries in the registry to start whatever, and later when you uninstall that software, and/or when that software is updated, files may be removed but the registry entries are left in place. Since the files aren't there they can't start anyway, so in this situation the only downside is they can add up to create registry bloat, making the registry larger than it has to be. More serious, at least potentially, are left over drivers. Drivers are a special kind of software that lets an app or apps talk to your hardware. And drivers are more prone to cause crashes and BSODs than anything else. Worse, they can be difficult, sometimes even impossible to remove/uninstall. That's why you should be careful while run an auto antivirus scan, clearing the wrong checkbox in Autoruns can break Windows Permanently.

If the driver Tcpip.sys becomes corrupted or outdated, your computer will encounter Tcpip.sys error and related errors, the most effective method to completely get rid of the problem is to run a free scan for Tcpip.sys error and its related errors as soon as possible. It is recommended to use DLL Suite, which has a built-in feature of Fix BSOD caused by .sys files error. This DLL Suite uses its own records of what should be removed from the hard drive and in the registry, ensuring that the problematic driver file and the related file error are fixed properly.

When you need to fix .dll missing error, .exe virus infection and .sys blue screen of death, or download missing or corrupted DLL files for free, please just pick DLL Suite.

Download DLL Suite install and run, then click DLL Suite's Dashboard menu > Click Scan DLL Errors button > Click Fix DLL Errors button after the scan, and the blue screen or any other sys file related error will be repaired automatically.

  1. WILLIAM LOSCH replied on February 15, 2013: » You appear to have two real-time third party security software installed, PC Tools and McAfee.

    Either one can cause issues with the tcpip.sys or related "networking" drivers.

    Running two real-time antivirus and/or firewall software can also result in conflicts between the two products, I would suggest to uninstall both PC Tools and Mcafee and see if the BSODs resolve, Afterward install just one security software.

  2. ANTHONY AGUINO replied on February 15, 2013: » Let's uninstall Mcafee, Spyware Doctor and PC Tools and watch the machine's behavior.

    Please note: Sometimes it is necessary to download a removal tool from the manufacturer to get these programs completely uninstalled.

    Further, you will need to choose one of these softwares to put back on the machine eventually as these programs do not always play nicely with each other. All of this being said, it was PC Tools in the stack.

  3. ANTHONY NALEPA replied on February 16, 2013: » I've disabled PC Tools, but it will be a few hours before I know if that is the cause or not. It sounds like a likely culprit - I used to run both simultaneously on my old laptop, which is why I had not suspected this as a problem, but hopefully your advice will solve the issue.

  4. MARIELA FUENTES replied on February 17, 2013: » Using Windows, to search for drivers, is not always the best idea. There have been instances of it finding the wrong one.

    If the computer is branded, as this one is always go to the site - ie Samsung, Dell, etc.

    If anything has been added, although it does not of course apply in your case go to the manufacturers site for the addition. ie: Nvidia for graphics etc.

  5. MARCELO SANTOS replied on February 19, 2013: » These problems sometimes occur due to file corruption. Run Disk Check with both boxes checked for all HDDs and with Automatically fix file system errors checked for all SSDs.
