ASP.net 2.0 Execute server process "request failed"

[brownie]

Hi PPL,

ASP.Net 2.0, IIS 5.0 on W2K Server SP4

I am attempting to execute a process on the server via an ASP.Net page but am receiving the following error:


System.Security.SecurityException: Request failed.
at System.Security.CodeAccessSecurityEngine.ThrowSecu rityException(Assembly asm, PermissionSet granted, PermissionSet refused, RuntimeMethodHandle rmh, SecurityAction action, Object demand, IPermission permThatFailed)

The action that failed was:
LinkDemand
The type of the first permission that failed was:
System.Security.PermissionSet
The Zone of the assembly that failed was:
MyComputer


Web.config has the following 3 settings:


<identity impersonate="true" />
<anonymousIdentification enabled="true"/>
<trust level="High"/>


I am using an System.Diagnostics.Process instance. Both the IUSR and ASPNET accounts have execute privileges on the executable file. When I step through in code the function does not seem to be called. When I try to 'step into' the function the error is produced before I actually get into the function - its like its not even called.

I added the following attribute to my ExecuteProcess routine:


<System.Security.Permissions.PermissionSet(System.S ecurity.Permissions.SecurityAction.LinkDemand, Name:="FullTrust")> _


No success...

Obviously this is a security permissions problem. How do I fix it?

Thanks everyone,
Matt.:confused:
