Help, I have a weird Excel / networking issue that I need a hand with. The Network: 1 x G5 iMac 10.3.8, running Office 2004 with latest patches sharing the contents of its "documents" folder. Connected via AirPort to an Airport Extreme base station. 1 x G4 iMac 10.2.8 and Office 2004 with latest patches connected via Ethernet to the Airport Extreme base station. 2 x G4 iBooks (both 10.3.8 and Office 2004 with latest patches) connected via AirPort to the AirPort Extreme base station. The G4 iMac and the iBooks connect to the G5 as the owner so permissions should not be an issue. The Issue: The G4 iMac is fine. It can open any Office (or any other document) without problem. The G5 iMac is similarly fine. The iBooks though have an issue. The iBooks can open Word and PowerPoint documents without any issues. However attempting to open Excel documents results in an error message: "The file Excel Test1.xls 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 or may not be responding. Cancel / Retry" If the file is copied from the G5 iMac to either iBook the file opens fine. I used my PowerBook as a control and logged onto the G5 iMac via the AirPort and was able to open the Excel fine without problem. This would suggest an Excel issue rather than a networking / permissions issue. Actions to date: So far I have: Rebuilt permissions on the iBook. Result: no change. Deleted the Excel plist files off the iBook and created them afresh. Result: no change. Deleted Office 2004 entirely and re-installed (including running the SR1 and Junk mail updates). Result: no change. Re-applied the access privileges on the G5 iMac. Result: no change. Any thoughts - flashes of brilliance or do tell them to buy Apple Works? -- Regards, Mark (}-: +61 (0)4 1927 7198 Skype / AIM / iChat: gibsonm1 Guy 1: "Man, you have a horrible virus on your computer!"
