Dear All,

I am doing:

            Dim f As New IO.FileInfo(FileFullPath)
            Return f.Exists

However, if:

FileFullPath = "\\COMPUTER_NAME\FOLDER\FILENAME.PDF"

Which lets says exists on my network, I am getting f.Exists as false, although the machine I am running this on can open that file if I go to Start > Run. Is this a permissions thing? Do I need the ASP.Net account on this machine to have read access to the files on that server?

Any help much appreciated.

Thanks,

Ben.

Please remember this command is executed on the IIS server as part of .Net and not on the local machine...

Depending on your security you will need to grant permissions to the FileFullPath as follows;

Application user's userid 'Needed if using impersonation...  
\NetHost\aspnet  ' Needed if using windows authentication
\\NetHost\IUSR_NetHost 'Needed if using anonymous authentication

Have Fun,
Dante

The site is using Forms authentication.

I am running the site on my development machine, i.e. the IIS of the site is on my machine, however, the files are located in another machine.

Forms authentication is used when running .aspx pages and is not used when loading non .Net pages...

Chances are you are not using impersonation because system would take on your UserID and perms when run so please;

In my example please replace NetHost with the name of your development machine and grant permission to the following userids on the FileFullPath  ("\\COMPUTER_NAME\FOLDER\FILENAME.PDF") file to:

\\NetHost\aspnet  
\\NetHost\IUSR_NetHost

Have Fun,
