Marcos - there are some real network experts around this list but I'm not one of them. To me the error message appears to indicate that the path to the files of the DP application is being lost along the way. My first question would be how you're directing the .tmp files. I always direct the .tmp files to my local directory in order to keep them off the network directory.
