Vista - Error 6 Handle invalid

Get "Error 6 Handle invalid" when using dial up.
Has worked for months, suddenly i get this error message.

Tried unistall modem and re-boot to re-install but that didn't work.

I saw this fix on onther forum concerning 2000 pro OS:


"I resolved this problem by removing the modem thru Control Panel > Phones and Modems and then I unistalled the modem in Device manager. Once the reboot was complete and it was reinstalled it was working again.
When you look on Control Panel > Phones and Modems you will notice that you see the modem is "not present" on any ports. If you try just unistalling thru Device Manger it won't work."


Since the OS is different than VISTA, you can't follow the path exactly, but I thought
this may help.

Others have tried a restore to time before the problem but that apparently didn't work
(Although I haven't tried it myself yet)

Okey, if anybody knows what to do, PLEASE let me know here!

Hi and welcome to the Vista forums!

Can you go in device manager, display hidden devices, have a look in network and modems to check if all device seem to work fine.

Not sure what you are getting at with the above.

Anyway, ran modem test; tested fine.
Set up another dial -up with phone #, password and username, that didn't work!

I use the same account info to get on line with my old MAC so I can post here today.

Uninstalled modem and re-installed by re-boot; that didn't work.

HELP

Maybe i explained myself badly.
In device manager, if you show all devices including the hidden devices, do you have any yellow mark in front of a device?

Thank you for the help!

The large list of Network adapters "6TO4 Adapter", isatap, WAN, etc. all have the yellow triangle with !


I don't know if that means anything.
Thanks for the replies.

There must be something wrong with the modem drivers?

The 6TO4 adapter is in relation with IPV6 it enables to transport IPv6 traffic over an IPv4 infrastructure.
So apparentely there is no relation between your problem and this adapter, M$oft saying that the yellow mark do not affect in any way the network process.... ????
My point of view maybe different so let's try to install the right drivers manually.

First, what is the error N° shown in the adapter properties?
Then make this test: Remove all the 6TO4 adapters (uninstall) then reboot and have a look in the devices manager, how many adapters are reinstalled?
If only one with the yellow mark, launch your dial up connection, it won't work obviously, close it and have a look again in the devices manager to check if the number of adapters has changed.
Seems a bit silly to check that but i have something in mind

ALL the drivers listed under Network adapters have the yellow triangle and under properties says "Windows cannot load the drivers required for this device (code 31)

There are 17 6TO4 adapters listed with the yellow triangle but do not disapear when "uninstalled".

Yep, but please go on with what i wrote in my previous post.

When you "uninstall" the missing driver, nothing happens.
I re-booted, everything is the same.

Weird!
Then, try to install manually the driver.
Choose to install a driver from your computer, then choose within a list on your computer, then untick "display compatible hardware" or something like that, then choose Microsoft (not microsoft corporation) and click on the 6TO4 adapter and try to install it!
