The following is a re-post of our post to the SBS2K Yahoo list:
First place to start would be with their Network Test Tool. It will give you the full host of things missing/broken between the client and the server.
- Make sure the database manager is up to date and the exceptions are in the firewall on _both_ the server and the clients. We use a custom GPO setup for QB/Simply/LoBs.
- Whatever the latest one is should be the only one running.
- We have disabled the earlier versions in Services.msc only to have QB Database Manager re-enable them.
- Make sure that the QuickBooksDB22 or whatever has Read/Write at the NTFS level (we set share to EVERYONE=FULL) for the QB company files.
As a rule we have not had to mess with anything network related on SBS 2008/2011 Standard to get QB working.
