Let me brief you what I was trying... I work on Visual Studio 2005 / MS-SQL / C#.

The error what I get is:

Where are you trying to write files? Some folders require more access than others.
Have you tried run as administrator?

Thank you for your response.

I was trying to pick up a file from the server folder (using server.mappath) and send as an attachment using asp.net mail.

Does your site have file i/o permissions for the folder in question?

[laxatcg1]

Yes and I have even given full permission to the folder and the files.

Try mapping a folder and using it's drive letter

[laxatcg1]

Thank you for your response...

Yes I have mapped to the complete path including the drive letter...

by the way, you checked out what path\filename you got after server.mappath... to be sure you really got the phisical path and filename you needed?
