This question was asked of me earlier today, about 5 hours ago. I'm using ACAD 2004 MAP and could not figure it out. I instructed the operator to disable digital signatures and run the exe to disable it. no difference. The explorer and other programs (word and excel) see and open the files on the NETWORK at the regular access speed. THe MIS Person has recently up graded the server and that's when the operator started having the problem. The operating system is XP Pro, the network is NOT novel. What can be the Problem/s?
