Hi thanks for the replies.
You are correct that the button is 'Publish' not Finish.
In the design view of the form I'm trying to publish through the design task menu on the right-hand side using the sixth item 'Publish Form Template' on clicking publish after a short delay I get the error message. The design form is set to restricted security.
The thing I have noticed after some investigation this weekend is that in form view, when filling, out a form I can send via Email 'File menu - send to mail recipiant' with no errors, using restricted security. also I have set submit button to via email and in form view this also works. It also attaches the xsn file.
I have also aske the system administrator to enable our system so I can use domain security to see if this gets rid of the error when publishing from a design view, but he has no idea how to do this. Therefore looks like I will never be able to connect to an SQL database.
Thanks for your help it is appreciated by someone new to infopath.
Mark.
