We have a pc running Vista Home Premium and have successfully mapped a drive to our Snap Server 1100. However, when the use puts files on the Snap Server is the shared folder, he is no longer able to access them - message received is: "(filename) cannot be accessed. The file may be read only, or you may be trying to access a read-only location, or the server the document is stored on may not be responding." Other users access the snap server from various computers - macs and pc's running XP. This is the only vista machine connecting. Is this a vista security issue?
