We have a Windows 2012 Server Hosting many QuickBooks database files. People have lost the ability to open the Company files in Multi-User Mode. They are getting a H202 error within QB.
I have been in contact with QB Pro Advisor Support and they could not resolve this problem?
Verified no one is Hosting any Company Files on their Computers.
Verified All QB Services are running on the Server:
QuickBooksDB23. DB24, and DB25
When I run the Scan from the QB25 DataBase Server Manager on the Drive and Folder Hosting the Company files, it ends with an error stating " Windows firewall is blocking QuickBooks"?
I have input the Exceptions in the Windows Firewall as per QB Support. I've tried disabling the Firewall. I have disabled AVG CloudCare on the Server.
The server is a Small Business server that is a "Everything Server-Domain Controller", Active Directory, DNS, DHCP, File Server, Printer Server. It is in the Domain Controller OU in AD. I tried Blocking GPO Inheritance on that OU.
I found this interesting article on my problem and simular in nature: http://blog.cypgrp.com/2014/06/12/so-you-cant-get-quickbooks-to-work-in-multi-user-mode-on-windows-2014-r2/
but it did not resolve my issue. When I did try to Restart the "Base Filtering Engine" Service it locks out Everyone from accessing the server over the Network. That doesn't seems right.......
I am at my Wits-End, Please Help!
