Ok, I am sorry to say I do not follow what you are saying.
You get an error when you try to login ? How do you mean it has to create a session otherwise (correct spelling) it gives an error?
Here is what I would do:
1. I would Recreate a new project, new directory, and build it in stages. i.e. Paste in the HTML code, and compile the code. Paste in the VB.Net code, complie, etc... that way you will see any errors that come up in the code.
2. Provide the error message you are getting and I may be able to give more details.
As I told millers_35, I am really stumped. I have done this same application about 20 times on numerous machines to boot with no issues like this.
Sorry I couldn't provide more help.
On that note, have you tried doing a simple ASP.Net page, like retrieving data from the db? i.e. Create a simple datagrid populating with a simple select statement?
i have the same problem as millers_35 i do the authorization and if it returns true i redirect to the default.aspx and create the session (ok other way round first session then the redirect) as put in the tutorial so it can only redirect if i am logged in and it has to create a session otherwhyse it msu give an error. ok so i am on default then and the session is disapeared :-( ... i am geting realy frustrated about this. do you have any idea on what is going wrong ...btw i get the same problem on my real webserver hosted by easycgi so it cant be a settingsproblem of my iis
