Is DFS involved? We had a similar issue with pdf. Opening from a dfs share - \\comp.com\dfs\share\pdf.pdf wouldn't open, but \\comp\dfs\share\pdf.pdf did. (note the missing .com). Also, strangely enough, even with the longer path, we could make a copy of the file and it opened fine.

The error he gets is: "There was an error opening this document. The network path was not found." I am able to duplicate this on another Win7 machine in our AU office. This started happening after this past weekend, during which we switched from a Server 2003 VM to a 2012R2 VM. I've asked him to verify the version of Reader he's using. I installed 11.0.09 on my test machine over there. I also turned off "Enable Protected Mode at startup", per several web sites. Interestingly, he can open the PDF if he copies locally, or to a share on the file server in his office, and I can open it just fine from the US file server also. It's only across the WAN that it fails. Anyone else run into this, and have any insight? Kurt
