Error H101</h2> <h2 class="mb-2 mt-4 font-display font-semimedium text-base first:mt-0">Step 1: Verify Hosting Settings</h2> <ul class="marker:text-quiet list-disc"> <li class="py-0 my-0 prose-p:pt-0 prose-p:mb-2 prose-p:my-0 [&>p]:pt-0 [&>p]:mb-2 [&>p]:my-0"> Open QuickBooks on every workstation. </li> <li class="py-0 my-0 prose-p:pt-0 prose-p:mb-2 prose-p:my-0 [&>p]:pt-0 [&>p]:mb-2 [&>p]:my-0"> Navigate to File > Utilities. </li> <li class="py-0 my-0 prose-p:pt-0 prose-p:mb-2 prose-p:my-0 [&>p]:pt-0 [&>p]:mb-2 [&>p]:my-0"> Make sure only the server computer has the option “Host Multi-User Access.” </li> <li class="py-0 my-0 prose-p:pt-0 prose-p:mb-2 prose-p:my-0 [&>p]:pt-0 [&>p]:mb-2 [&>p]:my-0"> If a workstation shows “Stop Hosting Multi-User Access,” disable it immediately. </li> </ul> This ensures that only one computer acts as the host, preventing conflicts. <h2 class="mb-2 mt-4 font-display font-semimedium text-base first:mt-0">Step 2: Create a New Network Data File</h2> <ul class="marker:text-quiet list-disc"> <li class="py-0 my-0 prose-p:pt-0 prose-p:mb-2 prose-p:my-0 [&>p]:pt-0 [&>p]:mb-2 [&>p]:my-0"> Locate the company file folder. </li> <li class="py-0 my-0 prose-p:pt-0 prose-p:mb-2 prose-p:my-0 [&>p]:pt-0 [&>p]:mb-2 [&>p]:my-0"> Find the .ND file associated with your company file and rename it (e.g., companyfile.nd.old). </li> <li class="py-0 my-0 prose-p:pt-0 prose-p:mb-2 prose-p:my-0 [&>p]:pt-0 [&>p]:mb-2 [&>p]:my-0"> Open QuickBooks Database Server Manager and scan the folder again to generate a new .ND file. </li> </ul> Doing this rebuilds the network configuration to allow QuickBooks to connect properly. <h2 class="mb-2 mt-4 font-display font-semimedium text-base first:mt-0">Step 3: Check Windows Firewall Settings</h2> <ul class="marker:text-quiet list-disc"> <li class="py-0 my-0 prose-p:pt-0 prose-p:mb-2 prose-p:my-0 [&>p]:pt-0 [&>p]:mb-2 [&>p]:my-0"> Go to the Control Panel on the server. </li> <li class="py-0 my-0 prose-p:pt-0 prose-p:mb-2 prose-p:my-0 [&>p]:pt-0 [&>p]:mb-2 [&>p]:my-0"> Click Windows Firewall > Advanced Settings > Inbound Rules. </li> <li class="py-0 my-0 prose-p:pt-0 prose-p:mb-2 prose-p:my-0 [&>p]:pt-0 [&>p]:mb-2 [&>p]:my-0"> Ensure QuickBooks ports (8019, 56728, 55378, 55382) are allowed through. </li> </ul> Without firewall permissions, QuickBooks Desktop won’t communicate externally. <h2 class="mb-2 mt-4 font-display font-semimedium text-base first:mt-0">Step 4: Use QuickBooks Database Server Manager</h2> <ul class="marker:text-quiet list-disc"> <li class="py-0 my-0 prose-p:pt-0 prose-p:mb-2 prose-p:my-0 [&>p]:pt-0 [&>p]:mb-2 [&>p]:my-0"> Open the server computer. </li> <li class="py-0 my-0 prose-p:pt-0 prose-p:mb-2 prose-p:my-0 [&>p]:pt-0 [&>p]:mb-2 [&>p]:my-0">

class="py-0 my-0 prose-p:pt-0 prose-p:mb-2 prose-p:my-0 [&>p]:pt-0 [&>p]:mb-2 [&>p]:my-0"> Restart QuickBooks services. </li> </ul> This restores the network link between workstations and the host computer. <h2 class="mb-2 mt-4 font-display font-semimedium text-base first:mt-0">Step 5: Edit the Host File</h2> <ul class="marker:text-quiet list-disc"> <li class="py-0 my-0 prose-p:pt-0 prose-p:mb-2 prose-p:my-0 [&>p]:pt-0 [&>p]:mb-2 [&>p]:my-0"> Get the IP address of your server system via Command Prompt. </li> <li class="py-0 my-0 prose-p:pt-0 prose-p:mb-2 prose-p:my-0 [&>p]:pt-0
