Re: ProcessStartInfo.WorkingDirectory and Mapped Network Drives

A windows service starts before anyone logs on. At that time, there are
no mapped drives. When you log on, you can see w:, but your service has
failed by then.
Services are designed that way on purpose - all the computer has to do
is start up. SQL Server is a great example - you can set it up, put the
computer in a closet, and leave it alone and still use SQL from a client
machine.

Thanks for the reply Bob. However, I have two comments/questions...

1) While running as a Windows Service, I can map a drive and access it
like
a local drive - it's just ProcessStartInfo.WorkingDirectory fails when I
set
it to a mapped drive. So, when you say "there are NO mapped drives" I
would
argue that there are...once you map them. Did I misunderstand your
statement?

2) In my code, ProcessStartInfo.WorkingDirectory doesn't like UNC paths
either. Have you experienced something different?

Until
someone logs in, there are NO mapped drives! So, you will have to use UNC
paths (//server/share1/dir1).

Just discovered a critical piece of the puzzle...

The Start() method fails, as described below, only when running as a
Windows
Service. When I try the same thing from s straight Console App while
logged
in as the service account user, Start() succeed. However, when running
as
a
Windows Service it doesn't seem I can set WorkingDirectory to any
mapped
drives...even though I have confirmed that the mapped drive does exist
and
is
accessible to the service account.

So, a refinement of my question should read "Has anyone successfully
set
ProcessStartInfo.WorkingDirectory to a mapped network drive while
running
as
a Windows Service?"

Has anyone successfully called the Start() method on a
System.Diagnostics.Process object with the object's
ProcessStartInfo.WorkingDirectory set to a path on a mapped network
drive?

For example, if I have "w:" mapped to "\\serverA\share1" and set
ProcessStartInfo.WorkingDirectory = "w:\dir1", my calls to
Process.Start()
always fail with the error "The directory name is invalid".

Whereas, if I do the same thing with WorkingDirectory = "c:\dir1",
calls
to
Process.Start() always succeed.

Before anyone asks, yes the directory "dir1" does exist on w: and is
readable under the user context calling the Process.Start() method.

If no one has successfully executed Process.Start() with
WorkingDirectory
pointing to a mapped network drive, does anyone have any (MS)
reference
article confirming that this is not possible and perhaps explaining
why?

Thanks in advance.
