What Causes Error Code H505 in 
QuickBooks Desktop?

take into account before attempting to resolve it:
• Error H505 occurs when several workstations, rather than the 
designated server, host the company file. This misconfiguration disrupts

• QuickBooks faces complications in acquiring the IP address of the 
system or server where the company file is stored, which can result in 
connectivity problems and errors.
