• Users on different computers can’t access the same company file.

• Performance is unusually slow in QuickBooks.

• The server hosting the file cannot be located.

Causes of QuickBooks Error H202

There are several reasons why you might see this error. Some of the most common include:

1. Incorrect hosting settings in QuickBooks.

2. Firewall blocking QuickBooks from accessing company files.

3. DNS server conflict or misconfiguration.

4. Damaged or misconfigured QuickBooks Database Server Manager (QBDBSM).

5. Incorrect network setup leading to communication failure.

6. Missing or corrupted .ND files that help QuickBooks locate the company file.
