I am using an excel spreadsheet, joining it to some data in my map. I have been able to join if i put the spreadsheet on my computer, but if I try to access it over the network, it will not connect. I get "failed to connect to database. General function failure. External table is not in the expected format. Can someone tell me why it will connect from my computer but not thru the nextwork? Is there a limit to the number of characters in the path?
