I have a client who has been experiencing an issue with their AutoCad. They are able to publish a drawing as a PDF or DWF to any server or locally fine the first time, but when they make changes to the drawing and try to save over the existing PDF or DWF, they receive an error that the file is in use by another user or process. I have verified the file is not open by looking at Open Files on the server they are saving to and by Using Process Explorer. This error even occurs after a server or workstation reboot.
It is more confusing in that they can do a "Save As" PDF just fine and even over write an existing file as long as they do a "Save As". The problem with this is the "Save As" only saves one tab (sheet) in the PDF whereas the publish can save all tabs (sheets) in one document.
This problem does not occur in older version of AutoCad like 2008 or 2009. It seems to only occur in 2010, 2011 and 2012. We are thinking maybe there is some underlying communication problem between our network and the newer AutoCad. We are running Server 2003 and Server 2008 in our domain. Our Domain Functional Level is at 2003 and the Domain Schema Master and holder of other FSMO roles is a 2003 R2 box.
