I get the following virtually daily at random times: Faulting application name: explorer.exe, version: 6.1.7601.17567, time stamp: 0x4d6727a7 Faulting module name: ntdll.dll, version: 6.1.7601.17514, time stamp: 0x4ce7b96e Exception code: 0xc0000005 Fault offset: 0x00032239 Faulting process id: 0x1b20 Faulting application start time: 0x01cca8b443c72113 Faulting application path: C:\Windows\system32\explorer.exe Faulting module path: C:\Windows\SYSTEM32\ntdll.dll Report Id: 808afa39-14a8-11e1-90f3-00265e93ae5a

Any backstory on what you were doing when the fault happened? Does it really seem 100% random, or can you narrow it down to certain actions or applications? Several people report this error when printing from Office products (Word, Excel, etc...). If so, does this happen when you print from Notepad or any other application? Or only within Office products? If it only occurs in Office, use Microsoft Update to update and patch your Microsoft Office applications.

It happens when I do file related operations in explorer... Open a directory... Delete a file... save a file... etc...

Hi, The issue should related with ntdll.dll file. The ntdll.dll file is a file created by Microsoft that has a description of "NT Layer DLL" and is the file that contains NT kernel functions. You may try to copy this file from a well worked machine and replace the old one. Also you can try to perform a Clean Boot to see if any third party services conflict it. There’s similar thread may helpful to you: http://social.msdn.microsoft.com/forums/en-US/ieextensiondevelopment/thread/5ab972c4-8924-4214-a314-e60080972b05/ Regards, Leo Huang Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

I replace my laptop with a new one only this time it is 64bit OS. This machine connects into my company VPN and I think it is possibly something in the group policies. I'm having the same symptom with the new laptop and new OS. ############################# ############################# ############################# I see the following: Faulting application name: Explorer.EXE, version: 6.1.7601.17567, time stamp: 0x4d672ee4 Faulting module name: ntdll.dll, version: 6.1.7601.17725, time stamp: 0x4ec4aa8e Exception code: 0xc0000005 Fault offset: 0x000000000004e4b4 Faulting process id: 0x163c Faulting application start time: 0x01cd4dd24a122a0e Faulting application path: C:\Windows\Explorer.EXE Faulting module path: C:\Windows\SYSTEM32\ntdll.dll Report Id: 76b2e103-ba2b-11e1-8c2b-402cf4b6db3b ############################# ############################# ############################# And before that error there seems to be this: Fault bucket 3031192604, type 5 Event Name: WindowsUpdateFailure Response: Not available Cab Id: 0 Problem signature: P1: 7.6.7600.256 P2: 80072efd P3: D67661EB-2423-451D-BF5D-13199E37DF28 P4: Scan P5: 101 P6: Managed P7: P8: P9: P10: Attached files: These files may be available here: C:\ProgramData\Microsoft\Windows\WER\ReportArchive\NonCritical_7.6.7600.256_31e239c46abafb1adf160ee31c3b513d5b18dfc_10f5f6c9 Analysis symbol: Rechecking for solution: 0 Report Id: ce61a8fb-ba24-11e1-8c2b-402cf4b6db3b Report Status: 0 ################################################# ################################################# ################################################# The following is in that file: EventType=WindowsUpdateFailure EventTime=129845939051921275 Consent=1 UploadTime=129845939052701275 ReportIdentifier=ce61a8fb-ba24-11e1-8c2b-402cf4b6db3b Response.BucketId=3031192604 Response.BucketTable=5 Response.type=4 Sig[0].Name=ClientVersion Sig[0].Value=7.6.7600.256 Sig[1].Name=Win32HResult Sig[1].Value=80072efd Sig[2].Name=UpdateId Sig[2].Value=D67661EB-2423-451D-BF5D-13199E37DF28 Sig[3].Name=Scenario Sig[3].Value=Scan Sig[4].Name=SourceId Sig[4].Value=101 Sig[5].Name=Environment Sig[5].Value=Managed DynamicSig[1].Name=OS Version DynamicSig[1].Value=6.1.7601.2.1.0.256.4 DynamicSig[2].Name=Locale ID DynamicSig[2].Value=1033 State[0].Key=Transport.DoneStage1 State[0].Value=1 FriendlyEventName=Windows Update installation problem ConsentKey=WindowsUpdateFailure AppName=Host Process for Windows Services AppPath=C:\Windows\System32\svchost.exe ReportDescription=A Windows update did not install properly.
