The information in this article is intended for Administrators or IT departments for Networks where Lacerte is installed. If you do not understand these settings, do not make any changes and contact an IT person. The settings found below have been found to help some customers, but each network is unique and may not apply to your situation.
Lacerte support agents will not perform any of these changes and are not responsible for the effects, they are informational only. These changes should only be made by IT personnel who have researched and reviewed potential impact of the changes to their network and taken appropriate precautions to prevent data loss or downtime.
Common Network Settings
Improving performance speeds
All network interface cards (including the server's) should have Large Send Offload Files disabled to ensure true gigabit speeds across the network. Lacerte performs slowly if network speeds go below 20MB per second.
To disable in Group Policy Object (GPO), follow this guide.
To disable manually on each workstation and server, you will want to disable Large Send Offload (LSO). LSO is an option located in a Device Manager in your network adapter's advanced settings, so this solution requires administrator privileges.
Follow these steps to disable LSO:
- On your Windows task bar, in the Search field at the lower left-hand corner, type Device Manager.
- You will see a list of all devices on your machine. Click on Network Adapters from the list shown.
- Double-click on your Network Card.
- Click the Advanced tab. You will see a list of options.
- Select Large Send Offload V2 (IPv4) and set the value to Disabled.
- Click OK.
- Reboot the computer.
- Repeat the above steps for each workstation.
Offline File Caching / Sync Center
Offline files or Sync Center should be disabled on any network share where Lacerte Data or Options are being accessed. On the server, the Caching setting in the Share's Advanced Sharing properties should be set to "No files or programs from the shared folder are available offline".

Network Drive Disconnects
This can cause several symptoms in both Lacerte and DMS including the program freezing, the client list showing all the same client, errors about saving, and database errors. There are several possible causes:
- Group Policy - Background refresh of GP has been reported to temporarily disconnect a GP defined drive when the Action is set to "Replace". Here are two possible solutions:
- Turn off Background Policy updates: Lacerte or DMS Stops Responding or Freezes in Windows 10
- https://technet.microsoft.com/en-us/library/cc770902(v=ws.11).aspx - change the Action from "Replace" to "Update"
- Idle Timeout - https://support.microsoft.com/en-us/help/297684/mapped-drive-connection-to-network-share-may-be-lost
- NIC Power Management - https://blogs.technet.microsoft.com/exchange/2013/10/22/do-you-have-a-sleepy-nic/
- Network Drives Not Visible in Lacerte Tax or Lacerte Installer- This can be caused by the programs running in Compatibility Mode or as Administrator and the Admin Profile not having the drive mapped. See linked article for settings.
The authentication window displayed when starting Lacerte uses an embedded IE webpage which requires cookies to be accepted for intuit domains. Group Policy may be set to restrictive to allow cookies and needs to be relaxed - see the following articles:
Terminal Server Performance
"FairShare" settings on Server 2008R2 and Server 2012 have solved performance problems with some users:
- Slow Terminal Server - article where author had experience with a similar app and settings he used to solve it.
A registry key can tell the program that it needs to reboot when you try to launch Lacerte. Sometimes this key does not clear after the reboot and the message keeps coming up. This article contains the key to clear.
