Make sure you have the computer name at the beginning of the file path. Also, doublecheck the file path address to make sure there are no typos. It should look something like this:
Computer Name\C:\Program Files\Avaya\IP Office\CCC\Delta Server\SMDR Output\SMDR(.csv
That is the basic idea, it might be a little different. I am going off of memory as my customer is logged on and I don't want to boot them off to check.
