We have an issue where we can edit a pdf document in SharePoint 2007 by clicking 'Edit Document'. This checks out the PDF document to the SharePoint Drafts folder. We can edit the PDF from within this drafts folder then save it back to this folder. However, when we go back to SharePoint and try to check it back in, we get an error. Please note that we have to follow the above process because we log into one server (GIS) but the publishing site is out on another server within our DMZ. This is actually the second issue we have had with SharePoint 2007 and Adobe Acrobat 8. This first issue was when we clicked "Edit Document" from within SharePoint, the whole system would crash. We changed the default drafts folder and have to follow the above process (e.g. check out, go to drafts folder and edit PDF, then save. Go back to sharepoint and check it back in). What I'm wanting to know is whether anybody else has had the same issue where you could not check the PDF document back into SharePoint? If so, did you find a work around?

Your problem does not lie in the checking in/out of the document. Your problem lies in the implementation of your DMZ server. Something is not correct in trying to get to the DMZ server. If you tried this process on an internal SharePoint server, I am willing to bet it would work just fine. Track through the ULS logs and the Event logs of both servers to find what is causing the issue. My guess is that there is a port not opened from the DMZ that is causing the failure. I trust that answers your question... Thanks C http://www.cjvandyk.com/blog

Thanks Cornelius. You are correct - the process works fine on an internal SharePoint server. Would you happen to know which ports / services are required? We did not do the implemention.
