I am the IT Manager for several affiliated companies that use Quickbooks for accounting and inventory control. We currently have an application server setup at our home office that allows users in remote offices to log in and run the quickbooks apps. The server is an Intel XEON quad core 3.0 Ghz. with 8 Gig of Ram, running Windows Server 2003 (64 Bit). The users connect via Terminal Services.
It had been working pretty well until the last few weeks, during which time we upgraded form Quickbooks Enterprise 9.0 to Enterprise 11.0 and increased the number of remote users from about 4 to around 15 to 20. It is now very slow when accessing a particular company file that is over 500 meg in size.
I think it is time to upgrade the server and software, but I am not up to date on the best way to configure an application server. Does anyone have any suggestions that may help me get started. I would appreciate any guidlines on hardware and software.
