How to find named pipes

[DBC User]

Hi all,

I would like to know is there a way to find out if any named pipes are
running in a box. How can I go about doing that? Or is there a way to
find out if a particular named pipe already running?

Thanks

Hi,

this can be done with (undocumented) api "NtQuerySystemInformation" but
it is not trivial to use this on .NET though it will work stable.

CreateFile with the device path to the pipe and OPEN_EXISTING should tell
you whether it exists or not (you'll either succeed, in which case it
existed, or fail with access denied, in which case it existed, or fail with
file not found, if it didn't exist).

Use the "processexplorer" from
http://www.microsoft.com/technet/sysinternals/utilities/processexplorer.mspx.
Select a process in the list and View Handles (Cntrl + H) and search for a
File handle with the device name of the named pipe you are looking for
(\Device\Named Pipe\....).

Thank you very much for everyone for the suggestions. This gave me lot
of insight into Named Pipe itself
