Unlike current versions, Filemaker 5 supported 3 different network protocols. Which are you using and have you configured your workstations and files to use the protocol you've selected?
First I left it at default, .. all 3 protocls on.. Then changed to TCP IP only - no joy either way.
Our network uses TCP IP and Netware ..
Are the files set in Sharing to be multiuser or single user?
In application preferences, what network protocol has been selected? (You'd check this on every machine where you've installed FileMaker.)
Currently I testing on only one PC - mine. FM is set on all machines to use TCP and files are multi user.
(In fact, there are only 2 of us using these files at present. )
Will follow up tomorrow..
My Novell also uses TCP / DNS
I know there are just 2 users (right now) but there are other files and users I was going to include.. and it looked simple enough.. now I just want to beat it into shape. Never accept defeat from a machine.
We're a bit handicapped in helping you given that Server 5 is 6 releases old.
