I am having a problem with multiple workstations on LAN running Office/Excel 97 under Windows 2000 Pro. When an saved excel doc is opened, an error message is displayed: "A document with the same name is already opened. Please close the document and try again." The user may then proceed normally, with the document open and fully functional. It seems as though Excel is trying to open the file twice? I have tried reinstalling Office 97, copying the registry keys from a working machine to an affected machine, and checking the alternate startup folder to make sure it is blank. Antivirus definitions are also up-to-date. I could not find anything pertaining to this type of problem on Microsoft's knowledge base. Any ideas?
