Hello Can anybody help? We have two WinTime systems that have L6 TCP/IP terminals where we get the message 'Invalid booking record' in Goldwin when Goldwin is trying to download the booking data from the terminals. With the first customer with the problem, the system was originally installed on a Windows95 PC, and everything was working correctly. We then transferred the system to a WindowsXP PC, and the problem started. With the second customer with the problem, the system was originally installed on a WindowsNT PC, and everything was working correctly. We then transferred the system to a Windows2000 PC, and the problem started. (We have many installations on Windows2000 and XP that are not experiencing problems with similar configurations). What seems to happen is that when a L6 TCP/IP terminal has stored a number of bookings in the terminal (this number can be as little as 29 bookings, but normally over 40), Goldwin is unable to complete the download of the booking data. Goldwin connects to the terminal and polls it normally. The number of bookings in the terminal is displayed as normal. The message 'TCP notification: READ' is displayed repeatedly (this depends on the number of bookings in the terminal, but usually four times), then the message 'Invalid booking record' is shown, and the data is not downloaded. When this occurs, we have to use HTS32 to download the booking data, and use Goldwin to import it from the saved file. No errors are reported during this process, leading me to believe that the 'booking record'/data in the terminal itself is not invalid/corrupt. It is almost as if 'something' interrupts the data flow from the terminal to Goldwin, which Goldwin then interprets as an 'Invalid booking record'. Finding out what this 'something' is that is interrupting the data flow is very difficult to find! We have tried manipulating the timeouts, tested various terminals, and we cannot solve the problem. I am inclined to think that the WinTime/Goldwin software, the L6 TCP/IP terminals and the customer's physical network cabling are not the problem, as they were working correctly under W95/WNT, but are having problems with W2000/XP. That would leave us with some kind of problem/conflict with W2000/XP/the new PC hardware with the LAN cards in the L6 TCP/IP terminals and/or the customer's network. It also appears that Goldwin can download a larger number of bookings sucessfully during times when the LAN/WAN is experiencing less traffic (such as during lunch periods when more staff are not using the network). The customer, of course, says that there is nothing wrong with any of their equipment! Any comments/questions would be welcomed.
