Remove network connection

Jonas

I want to remove a remote access connection when a user logs out. The
connection is a dial up isdn adapter.

I can access the adapter via WMI namespace \root\microsoft \homenet, but i
don´t find any way to delete it.

Is it possible to do this or do i need to some pinvoke on rasapi32?

Hi,
I'm sorry that I am not sure if you want to close the connection or delete
an entry when a user logs out. Could you please lighten me more on your
issue?

Anyway, according to my experiences, RAS API is required on this issue and
the P/Invoke technology provides the appropriate way on .NET platform.

Firstly, you can use RasEnumConnecti ons to emumerate all the available
active RAS connections handles on your system; Then use RasHangup to close
the connection by the handle.
If you wanted to delete the entry, please use RasEnumEntries to retrieve
the available entries, then use RasDeleteEntry to delete the entry.

For the RAS API references, please refer to:
Remote Access Service Functions
http://msdn.microsoft.com/library/de...us/rras/rras/r
as_start_page.a sp

Please feel free to let me know if you need further research on this issue.
It's my pleasure to be of assistance.

Sincerely yours,

Hi.

I want to delete the connection.

I will try with the RasDeleteEntry, do you know any way to accomplish this
via WMI?

Hi,
Thanks for your response.
Please forgive my confusion regarding your saying "delete the connection",
because generally we say that close a connection or disable a connection.
Did you mean that?

Unfortunately WMI is not designed to be able to disable a network
connection.
From this article,
https://msdn.microsoft.com/library/d...-us/wmisdk/wmi
/wmi_tasks__netw orking.asp
we can see that:
If you're using DHCP, you can use the Win32_NetworkAd apterConfigurat ion and
the ReleaseDHCPLeas e method to release the IP address. If you are not using
DHCP, you cannot use WMI to disable a network connection.

If you have any other questions or concerns, please feel free to let me
know. It is my pleasure to be of assistance.
