Process.Start in a web service

[Josh Buedel]

When an ASP.NET app calls Process.Start(), is the resulting process run
under the same user as the ASP.NET app?

My situation is an ASP.NET app that calls out to an external exe. The
external exe uses a DSN entry and ends up getting the error "Microsoft][ODBC
SQL Server Driver][SQL Server]Login failed for user '(null)'. Reason: Not
associated with a trusted SQL Server connection."

The call to Process.Start() works perfectly in a non ASP.NET app.

I do have <identity impersonate="true" userName="DOMAIN\jbuedel"
password="mypassword" /> in web.config.
The DSN is set up to use a trusted connection.
I do have the SQL server set to mixed mode authentication.
The code "new System.Data.Odbc.OdbcConnection("DSN=JOSHDSN").Ope n();" did
not throw an exception when run in the web service (just before the call to
Process.Start). I believe this means my web service was able to use the
dsn.
Process.Start() doesn't throw any security exceptions (before and after
adding <identity/> to web.config).

How do I get the security 'context' passed down to the external app?

Thanks,
Josh

the shortest/simplest way to solve this is to create a dummy component in
COM+ give it the identity you want make it create the process and call it
form the web service.
