We have had all sorts of problems with files dissaparing......10.4.4->10.4.6
Suggestion from apple was to disable Spotlight on the server.
We have found that we have had problems with Photoshop 8.0 and 10.4.5 server running with 10.4.4 Clients. An error was comming up, saying that there was write access was denied. Disbaling spotlight on the client machine on the server seemed to fix this problem. Maybe someone with Photoshop 9.0.1 and 10.4.6 would be able to try disabling spotlight and seeing if that helps?
PS : I have noticed that under 10.4.6 the apple share client files are updated by both the 10.4.6 update and also the quicktime update. This casued all sorts of problems, when attempting to connect to an AFP server. So these files could well be an additional issue, for those of you with 10.4.6 installed.
My reccomendation is try editing the /etc/hostconfig file and change spotlight to NO rather than YES. Then reboot and see if the problem persitsts.
