I am trying to install a new site on our Windows 2003 server machine but every try gives me the error message "Error - ASPNET is not a valid user or group".
This seems very strange since this is a Windows 2003 machine which doesnt use the ASPNET account. Does anyone have any idea why this is occuring?
That sounds strange, 2003 sever does not have the aspnet user... Which version are you trying to install? And are you using the SDK installation, or the manager?
It is the EPiServer Installation manager from the latest R2 release.
If you by Clean mean a new web site then no. I tried to install it as a virtual directory under an existing web site by providing an application name.
I'm not sure exactly what you mean by manualaspnet_isapi.dll. I have checked the "ISAPI filters" tab on the website and that was empty and if I click the configuration button on the web site there is no such dll in the Application extensions list.
Did you resolve this? I have the same problem with a Windows 2003 Server, and I get this error after I have put all the credentials into the Installation Manager with R2 and start to install a web site.
This looks similar to the problem I had, see
