I have both ASP 1.1 and ASP 2.0 installed in my Windows Server 2003 with IIS 6.0 (Plesk). I noticed in the Services Manager that ASP.NET State Service (aspnet_state.exe) belongs to the ASP 2.0 directory. One of my client has an ASP 1.1 application and it doesn't word correctly due to session state not preserving the values after submitting a form. So how do I start aspnet_state.exe for ASP 1.1 ? I tried starting it manually, but doesn't work. Any idea what can be done ?
