Dear all, since some weeks i´m not able anymore to open network settings on Win 7 64bit Ultimate. If i move the mouse over the network icon (right corner), windows explorer crashes with following event ID: Protokollname: Application Quelle: Application Error Datum: 21.07.2010 14:17:17 Ereignis-ID: 1000 Aufgabenkategorie:(100) Ebene: Fehler Schlüsselwörter:Klassisch Benutzer: Nicht zutreffend Computer: xxxxx Beschreibung: Name der fehlerhaften Anwendung: explorer.exe, Version: 6.1.7600.16450, Zeitstempel: 0x4aebab8d Name des fehlerhaften Moduls: wwanapi.dll, Version: 6.1.7600.16385, Zeitstempel: 0x4a5be0a8 Ausnahmecode: 0xc0000005 Fehleroffset: 0x00000000000175c4 ID des fehlerhaften Prozesses: 0x1b74 Startzeit der fehlerhaften Anwendung: 0x01cb28cea269d482 Pfad der fehlerhaften Anwendung: C:\Windows\explorer.exe Pfad des fehlerhaften Moduls: C:\Windows\system32\wwanapi.dll Berichtskennung: e6b07065-94c1-11df-9948-001a6baf106a Ereignis-XML: <Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event"> <System> <Provider Name="Application Error" /> <EventID Qualifiers="0">1000</EventID> <Level>2</Level> <Task>100</Task> <Keywords>0x80000000000000</Keywords> <TimeCreated SystemTime="2010-07-21T12:17:17.000000000Z" /> <EventRecordID>10954</EventRecordID> <Channel>Application</Channel> <Computer>M0471</Computer> <Security /> </System> <EventData> <Data>explorer.exe</Data> <Data>6.1.7600.16450</Data> <Data>4aebab8d</Data> <Data>wwanapi.dll</Data> <Data>6.1.7600.16385</Data> <Data>4a5be0a8</Data> <Data>c0000005</Data> <Data>00000000000175c4</Data> <Data>1b74</Data> <Data>01cb28cea269d482</Data> <Data>C:\Windows\explorer.exe</Data> <Data>C:\Windows\system32\wwanapi.dll</Data> <Data>e6b07065-94c1-11df-9948-001a6baf106a</Data> </EventData> </Event> Any hints? Everything is working fine with exception of network settings .... Thx, Lars

Hi Lars, do you use WAN networks? Which network cards do you use? Also please download this reg file from my SkyDrive: http://cid-128fc518635be2dc.skydrive.live.com/self.aspx/.Public/MS%20Foren/Registry/WER%5E_Explorer.reg and make a double click on the file to import it. When the Windows Explorer crashes, Windows Error Reporting Service [1] creates a dmp file under C:\Localdumps. Please upload the file to your public Skydrive [2] folder and post the link here. I take at the dump, maybe I can see the cause.

Hi André, thanks, i´ve uploaded the dumpfile to the following location: http://cid-94f236e4a63f9846.skydrive.live.com/redir.aspx?resid=94F236E4A63F9846!234&Bpub=SDX.Docs&Bsrc=GetSharingLink Thanks, Lars

Sorry, forget to mention the details for the WLAN adapter: Broadcom 802.11 Multiband Networkadapter (build in to HP 6710b)

This is mostly caused by faulty RAM. Please run a memory test [1] for at least 4-5 hours. André [1] http://www.memtest.org/"A programmer is just a tool which converts caffeine into code" CLIP- Stellvertreter http://www.winvistaside.de/

Hi, To check the memory, you may run Memory Diagnostics Tool or a third party tool, Memtest86+. If your memory is good, but the issue persists, I would like to suggest you run ShellExView and disable the third party shell software to test the issue. In addition, I also would like to suggest you download the latest version of the network card driver, uninstall the current installed one and reinstall it to check the result. Note: The third-party products discussed here are manufactured by companies that are independent of Microsoft.

Hi André and Arthur, well, memory diagnostic shows no errors. I´ve uninstalled and reinstalled the network driver. The issue still persists! Moreover, i´ve run ShellExView but i´m not 100% sure which 3rd party shell software to deactivate ... Thx, Lars

Hi Lars, The !chkimg extension detects corruption in the images of executable files by comparing them to the copy on a symbol store or other file repository. So, the downloaded file differs in 237 parts from the file found in the dump data! This means the file in the memory is modified. This MUST be a RAM issue. Did you use memtest86+ or which tool did you use? How long have you tested the RAM? Which mainboard/RAM do you use? Which timing does your RAM have? André"A programmer is just a tool which converts caffeine into code" CLIP- Stellvertreter http://www.winvistaside.de/

Hi André, well, i`ve used the integrated windows memory diagnostic tool. I´ll try the memtest386+ tool and run it for a couple of hours. Thx! Lars

test only 1 RAM module at each memtest86+ run."A programmer is just a tool which converts caffeine into code" CLIP- Stellvertreter http://www.winvistaside.de/

Well, i run this test for a couple of hours .... no errors!!!??? In the meantime WLAN doesn´t work anymore. LAN is fine ...

Change the Timing of the RAM. Have you installed the latest WLAN drivers? Which WLAN device do you use?"A programmer is just a tool which converts caffeine into code" CLIP- Stellvertreter http://www.winvistaside.de/

There is no possibility to change the timing within the BIOS settings. Moreover, it´s a Broadcom 802.11 Multiband Networkadapter with the latest driver. Honestly, i´m very close to reinstall the OS, but this would take around 2 days ... many progs and settings. Is there any possibility to "reinstall" the WWANAPI?? Thx!!

run sfc.exe /scannow from a command prompt (with admin rights). Does it detect corrupt files?"A programmer is just a tool which converts caffeine into code" CLIP- Stellvertreter http://www.winvistaside.de/

Hi André, yes, and it´s the second time that corrupted files have beend detected. It seems to be that some OS files have been corrupted ... :-( Is there any chance to repair the OS? Thx, Lars

OK, i´ve uploaded the cbs.log on skydrive: http://cid-94f236e4a63f9846.skydrive.live.com/redir.aspx?resid=94F236E4A63F9846!236&Bpub=SDX.Docs&Bsrc=GetSharingLink sfc wasn´t able to repair some files :-(

Does the same crash occur in Safe Mode? Also, what version of Office is installed and are you using the "Groove" or "Sharepoint Workspace" program?

Hello all, i´ve reinstalled Win7 by using an inplace upgrade to the same version. Now it´s working :-) :-) Thanks to all for help!!! Regards, Lars

Well, sfc /scannow is now 100% correct. All my settings have been saved. I think this is a way to fight against corrupted system files :-)
