Dear all, This is my first message here, I'm a rookie system administrator of a small office composed of Apple computers. All these computers are running Mac OS X 10.5.1. We also have a special (2GB of RAM) Mac Mini that we use as our OS X Server (10.5.1). Our server is providing basic networking services (Gateway, Firewall, NAT, DHCP, DNS, VPN) and it's also an Open Directory Master. Home folders of staff are stored in the server and get mounted on the workstation via AFP (aka Network Home Folder). Everything is working fine so far. But here starts my problem : Recently we've upgraded to MS Office 2008, and staff began to complain about problems while working with Word and Excel documents, I advised them to use the latest extension .docx or xlsx which seems to be more stable. Unfortunately for me the problems didn't stop. So I've checked it out by myself : Whenever staff try to open certain documents they get an error message that says "Cannot access <concerned file>" and click ok. After 2 or 3 attempts the file gets opened. Another issue is : Right away after closing a document, when staff try to open it again, they get an error message : "<concerned file> is being used by "another user". Do you want to make a copy ?" People from other Apple related forums told me it's a permission issue but i doubt about that because : 1) I haven't change anything to the default permission settings used for the Network Home Folder sharepoint. 2) If i use Apple's iWork, i get no problems, files open fine. Even the newly released Service Pack 12.1.0 doesn't fix any of these problems ! I really would like to get rid of these problems with Office '08 and stop hearing staff complains. I'm also wondering that i shouldn't be the only one having these problems since Network Home Folders and Office 2008 are commonly used in business (and my setup is about everything but special). Have you ever experienced the same issues : how did you solve your problems, any workarounds ? ... Thx a lot in advance !
