A small network with the file server/domain controller running MS Small Business Server 2003. The Macs could not talk to it at all when we installed the system 3 years ago. So on this server we installed an app from Group Logic called ExtremeZ-IP. This allows for administration of sharing for the Macs and apparently lets them understand NTFS, long file names, whatever. Life was good until we installed the Service Pack 2 on this server. Now, everything is exactly the same with one exception. We cannot save a file to any of the shares on the server. We can move, copy, paste, read, manipulate, do anything but save. Anybody experience anything similar after upgrading to SP2? By the way, upgrading to the most recent version of ExtremeZ-IP MIGHT fix this. But I don't want to pay over $1000 without knowing (pricey, yes?), especially when there might be a simple fix.
