dfssvc.exe is the Distributed File System service. It could be only found on Microsoft Windows Server editions, this process is crucial for the DFS service. DFS Service manages logical volumes distributed across many servers on a local or wide area network. Logical volumes enable the network manager in a large organisation to pool similar sets of data into single access points (one drive letter in Windows, ie. H: ) for the convenience of the users of that data.
