svchost.exe keeps throwing "unhandled win32 exception" errors

Recently I've been bombarded with Visual Studio JIT Debugger popup
error messages for no apparent reason. The messages generally read
something like:

"An unhandled win32 exception occurred in svchost.exe [xxx].
Just-In-Time debugging this exeption failed with the following error:
No installed debugger has Just-In-Time debugging enabled. In Visual
Studio...."

where "xxx" are usually 952 or 948 or similar.

Now if I enable JIT in VS.NET I'll be getting standalone windows
instead asking me if I want to debug with VS. In both cases (JIT
enabled or not) if I click on "OK" or "Yes/No" 2 things will happen:

1. my wireless modem will be killed and cannot be detected anymore,
meaning no more internet
2. same story with my audio - play movie and got no sound, and TV
capture program crashes because it can't detect audio etc.

Both of the problems above can be "solved" with a reboot.

Now I've since learned to leave those popups alone and move them out of
the screen and pretend them don't exist. That way I still get to play
with my internet and listen to music. Unfortunately since these
messages will come up on average every 5~10 minutes or so before long
you'll see 50~100 different instances of "vsjitdebugger.exe" in the
task manager, each taking up 100k to 3000k of memory, and the system
will become unbearably slow that I'll be forced to reboot.

I have just run deep scans of Norton AV and Adaware with latest updates
but found nothing suspicious. Does anyone have any idea how to find out
the cause of the problem and how to fix this? Thanks for any help.

Or if anyone can suggest a way to get my internet and audio back
without rebooting that would be great too.

Your system has a program installed, which is looking for a device it needs, that your system doesn't have. You need to locate that program and uninstall that program.

If you have the Sound Drivers installed and the system isn't detecting them, then open up Sounds in the Control Panel and click on Audio. Check the Default Devices selected for Playback and Recording.

I've the same problem since I installed Visual Studio 2005. When I
connect to the web through a proxy, windows update become erroneous.
and "an unhandled win32 exception occured in svchost.exe [****]"
exception is thrown which cannot be debugged. Yes it is sth relevant
to "Sound Device". Because "there are no active mixer devices
available" error is also given.

I have similar symptoms (happens when I try to expand 'My Computer', if I try to right click on a file in window's explorer and select

I believe that this happened after an SP2 install - perhaps I shouldn't have done but I was dealing with a new laptop set up by our IT admin with VS2005 installed and I couldn't build without installing...

When I look at the file permissions on rasadhlp.dll the user I'm using has read and execute permissions which seems right to me.
The version was in fact updated when I installed SP2: 5.1.2600.2938 (xpsp_sp2_gdr.060626-0020)

Any thoughts/solutions out there?

I am having the exact same issue as the OP.

I get unhandled exception errors as soon as my computer loads into Windows. I will have 15 waiting on me.

I also do not have any sound. It says no sound drivers are loaded.

I got the BSOD last night as well.

I tried booting in safe mode and running virus, malware and spyware and they found nothing.

What could be the problem here?

[TorS]

The problem is caused by Window Update client. If this prog is startet before the sound devices is properly loaded, this problem occures.
1. Deactivate the Windows Update (all options)
2 Reboot
3 Verfy that the Sound devices are loaded (ie start volume control)
4. Update Windows manually from the MS Win Update site.

If someone knows how to load sound devices before WU starts, please notify

The details related to your particilar problem are needed.

Have a look in the System and Application logs in Event Viewer for
Errors and Warnings and post copies here. Don't post any more than 48
hours ago.

You can access Event Viewer by selecting Start, Control Panel,
Administrative Tools, and Event Viewer. When researching the meaning
of the error, information regarding Event ID, Source and Description
are important.

A tip for posting copies of Error Reports! Run Event Viewer and double
click on the error you want to copy. In the window, which appears is a
button resembling two pages. Click the button and close Event
Viewer.Now start your message (email) and do a paste into the body of
the message. Make sure this is the first paste after exiting from
Event Viewer.

I had same problem. At level of 25 exceptions in 10 minutes...
It seems like the problem is not the exception, but the fact that VS in debug mode, close the program at the end of task. This appens in both cases you choose to debug or not debug the exception. If you click no, simply svchost was killed. If you debug that process, the killing actions take place when you stop the debug.

I have renamed the application debugger (vsjit.....) and so on system doesn't call any debugger for that exception.

Even with those exceptions, svchost still survive and nothing bad seems to appear. Sounds work and so on...

Simply rename the debugger vsjitdebugger.exe
Really, now i still have a problem with svchost.exe. Sometimes it crashes again, even after renaming. It occurs around one or two times in a day.

Anyway, i think the crash is caused by trojans. I have found one or two in my pc and i'm searching for the way to remove them. They produce several files named 06, 07 .... 64.scr
They write in System Registry bypassing alarms like TeaTimer and, i think, they produces some executable file that will launched at the successive startup.
For now i've found some trojans executable present at different time in the pc.
Names are:

dllcache.exe
$Username.exe
07.exe
MSSARV32.EXE

I'm almost sure that those viruses kill svchost.exe..

You need to post the BSOD error messages verbatim in your own thread.
That could be a hardware problem, with the hard drive, or its
controllers, perhaps. Do a test of the hard drive maybe. Open "My
Computer", right-click the hard drive, Properties, Tools, Error
Checking, "Check Now".

i agree with libertyfighter...

my system was infected by trojans... and i could see 15 svchosts running...

and from today morning i got this JIT dialog stating an unhandled win32 exception has occurred in services.exe ...

asking whether to set JIT the default debugger...if i say no then the system displays a small dialog in which it says the system will restart in 30 seconds...

and then it restarted...

i have installed windows live one and it is scanning the system... meanwhile if anyone could post their way of removing this ....

[vinodachu]

when an svchost.exe dies the services started by that particular svchost.exe also stop functioning. (like audio).if go on control panel -admininstrative tools-services and re enable the services .(for audio is windows audio service ).,you can avoid restarting your system
