Logon failure: unknown user name or bad password, on Response.WriteFile

excelf1 · March 11th, 2009, 09:48 AM

Hi all,
Within my website I obtain a lot of data from SQL, this works fine and the gridviews display without any problem.
However one particular grid holds 'newsletter/correspondence' in multiple formats. Whenever I try to open one of these files I recieve the below error. I'm at a bit of a loss as it's the same user set up with the same priveledges.
Does anyone know what I've done incoorect?
Logon failure: unknown user name or bad password.

This line right here: Response.WriteFile("\\" + e.CommandArgument.ToString()) this is just a guess since there isn't much to go on but, for whatever reason, the File or Directory you are trying to acess and subsequentially write to the HTTP Stream is not accessible to ASP.NET user. If this proves to be true you will either A) need to grant perms to the ASP.NET user or B)use impersonaition to access the file.

Hello,
I would like to add one more thing to the above reply.
Please check under which account your application runs (Basically application pool if your application is under any app pool -IIS6). It can be IUSR or can be some sort of service account also. Please give the read and write access to the folder from which you are trying to read the file.

For the sake of anyone else that might stumble across this thread what did the problem end up being and how did you resolve it?

Working fine. Please don't clutter the forums with test messages...
