I should wish this article to be of use to you for the solution of the problem

Click Start, click Run, and then type DCOMCNFG.
Click Component Services. Select DCOM Config on My computer.
Set the Default Impersonation Level to Identify (Impersonate also works).
Set the SecurityProperties of Your DLL. Assign the Launch and Activation Permissions, AccessPermissions to the ASP.NET running Identity
Save your setting and try your code again.

However, Microsoft does not recommend or support server-side Automation.
