The most common reasons behind Error H202 include: 1. Incorrect Hosting Configuration If hosting is enabled on multiple systems instead of only the server, QuickBooks cannot determine where the company file is located. 2. Firewall or Security Software Blocking Access Firewalls may block ports required by QuickBooks, preventing communication between workstations and the server. 3. Damaged or Incorrect .ND File The Network Data (.ND) file allows QuickBooks to access the company file in a network. If it’s corrupted, Error H202 may appear. 4. DNS or Network Issues Incorrect DNS settings or unstable network connections often trigger multi-user mode errors. 5. QuickBooks Services Not Running Services like QuickBooksDBXX and QBCFMonitorService must be running on the server. For complex network-related causes, it’s recommended to call 1-877-234-6881 for expert troubleshooting. <h3 style="text-align: justify;" data-start="3310" data-end="3346">Symptoms of QuickBooks Error H202</h3> You may be dealing with Error H202 if you notice: <ul style="text-align: justify;" data-start="3399" data-end="3590"> <li data-start="3399" data-end="3441"> Inability to switch to Multi-User Mode </li> <li data-start="3442" data-end="3484"> Frequent QuickBooks freezes or crashes </li> <li data-start="3485" data-end="3517"> Error H202 message on screen </li> <li data-start="3518" data-end="3546"> Slow network performance </li> <li data-start="3547" data-end="3590"> Workstations cannot open the company file </li> </ul> Ignoring these symptoms may lead to data access issues.
