Start External Process with Impersonate Issue

Im deploying my website onto my new server (windows 2003) from my local pc (windows 7) and my local homeserver (windows 2008) and have run in to a issue.

I have a process that starts up with the below code. It is passed a video file which gets converted.

System.Diagnostics.ProcessStartInfo StartInfo = new System.Diagnostics.ProcessStartInfo(Command, Parameters);

Them problem I have is on my new windows 2003 server it fails to work. No error or anything. Looking at the server and its taskmgr.exe I see the Process start but nothing happens.

Looking into it, everyone seems to say I need to have impersonate="true" in the webconfig which I do have, I currently have it set to the Administrator account which I use to log into remote desktop (I assume this is fine???)

<identity impersonate="true" userName="Administrator" password="********" />

This still doesn't work.. Looking in the taskmgr.exe the process is started with the username ="NETWORK SERVICE" ...

Any ideas???

Solution

A concrete solution i can't provide, but maybe this can help:

Take a low level look with Process Monitor to find if it is security related (missing permissions etc.)
Build a Debug Version of your programm and insert some Debug.Print() statements to narrow the problem. These messages can be seen bei Debug Viewer.
Maybe it's a problem with a wrong or missing assembly. To find these problem take a look into the Fusion Log Viewer.

Maybe one of these techniques will help you to tackle down your problem.
