Home Forums AC on it's own server?

Another option may be to move the AC "server" off the genuine server and onto another machine.
Do a full install/resintall on a machine (saying this is the main database)
Then open it up
and create a dummy system (must have one to do a restore)
then go to the AC folder and find Backup Restore Utility click on it
You then have to find the backup file in the original backup folder (unless you move a copy to that computer (makes life faster))
Then it will ask you if you want to override the current system (the dummy system) say OK
Then let it complete it's work
You need to go to Amazing Utilities in all the other computers and move them to see the database on the new main.

If this system works better, then you know it's not a network problem and perhaps a new server would help. If it's not better then it may be a network issue.

I agree with all the other comments above.
