Question : Urgent System.UnauthorizedAccessE<wbr />xception
|
|
Hi I have the following environment setup: on IIS server Anynomous user is checked (the account we used an account that has permission set on sql server example Corp\nxxyr password myPassword ) and also we have intergrated windows security checked.
On web.config we use impersonate =true.
The website have a part where a user uploads a file to the server (we also have a line of code that saves just the uploaded filePath to the DataBase). on the Server the upload folder is a shared folder out side of wwwroot. When ever the upload code gets executed the windows identity will changed to NT AUTHORITY\NETWORK SERVICE and the following exception is logged(P.S I think though not sure once the identity NT AUTHORITY\NETWORK SERVICE the application loosed its impersonated account that allows it to insert record to the db fails as well)
Full Exception:
An exception of type 'System.UnauthorizedAccessException' occurred and was caught.
