Hello again, Wes. Reference our brief telephone conversation last week (while you were in TX). I finally had some time to sit down and send you a follow up email request. I have two immediate issues for you: 1. VFP9 Performance Our software (an ERP), which is written in VFP9, performs very poorly over the network from a virtualized Windows 2012 server to a workstation running either Windows 7 or Windows 8. There is a big delay opening some screens. However, when our software is run directly on the server, or over RDP, the same screens open and perform 10 times faster, or more. Something is making network performance very poor for the VFP software. There are no issues with other softwares, by the way. The network is 1Gbps. No anti-virus software is running. The workstations and server have plenty of RAM and horsepower. 2. VFP9 crashes At a couple of different installations, some users run the VFP9 software directly over the LAN, while other users simultaneously run the VFP9 software via terminal services (RDP). The RDP users randomly experience crashes, while the LAN users have no such problems. The RDP users connect to a terminal server (Server 2008). When the crashes happen, the Event Logs show two errors, one right after the other: · Event ID 1000 (Application Error). The faulting application is our VFP9 software, and the faulting module is one of the following: VFP9R.dll; or mscrv71.dll; or ntdll.dll; or "unknown" · Event ID 1005 (Application Error). The note states, "Windows cannot access the file for one of the following reasons: there is a problem with the network connection, the disk that the file is stored on, or the storage drivers installed on this computer…" The IT Specialists have tested and re-tested the network infrastructure and its components. No problems are ever detected.Both of these issues seem to point at VFP9 having problems over modern network connections. Has anyone else had, or heard of problems like this?
Part 2: I have never seen the crashes you describe. VFP 9 has been rock solid in that effect. Also, I would note that I have customers running the application on the Windows Server 2012 with RTD only. We are using TSPlus for as many users as you need to access the server. I agree that it is significantly faster than the workstation arrangement.
