How to Fix QuickBooks Running Slow on a Network in Multi-User Mode
When QuickBooks runs slowly in multi-user mode across a network, it can interfere with workflow and lower productivity. Large company files, out-of-date software, network congestion, or incorrect server configurations are frequently the causes of this problem. Make sure the database server is configured correctly, that Windows and QuickBooks are up to date, and that the company file is kept on a strong, dedicated host system in order to resolve the issue.
