I've had this problem on more than one printer, so I believe the issue is to do with the computer that I intend to scan documents to.

On two different multifunction printers (HP and Canon), I've attempted to set up scanning to a share on a Windows 7 machine.

In the printer's web UI, it gives me options to put the computer's hostname (or IP), the share folder, and a username/password.

It doesn't matter whether I use hostname or IP, the scanner cannot connect to the remote computer.

I **can** ping the printer from the computer. Permissions **are** set up for the username that I've set up.

I'm wondering if there is some sort of firewall or antivirus issue blocking the connection, but I don't even know where to start. There isn't dedicated software I'm using to scan, it's just a direct Windows SMB scan.

As far as error messages go, on one printer I got a generic "Can't Connect" error. On the one I'm currently trying to set up (Canon), I get an "Error 806", which is a credential error, but I am absolutely positive I have entered the credentials correctly.
