  Re: import dll file does not work on 2003 IIS 6.0 Reply Contact On Windows XP/IIS 5.1, IIS worker process runs under "LocalSystem" that gives it much more permissions to do things. On IIS 6 by default, the process (application pool) runs under NetworkService. So you may open IIS Manager and change the application pool to run under NetworkService identity and test again.

  Re: import dll file does not work on 2003 IIS 6.0 Reply Contact So you have changed the pool identity from NetworkService to LocalSystem on IIS 6? Changing to NetworkService I think is not enough. This is not a thread limit, but a .NET security topic, http://msdn.microsoft.com/en-us/library/5ba4k1c5.aspx   Lex Li Support Engineer at Microsoft --------------------------- This posting is provided "AS IS" with no warranties, and confers no rights.

  Re: import dll file does not work on 2003 IIS 6.0 Reply Contact So there is no SecurityException, and just the packet was not sent. Then I think you need to review the native library being called. A recommended approach is to write some application log from the library so you can check out its execution path. Maybe something else is wrong.
