Check your network documentation. This error seems to occur at random times of inactivity on my application. Here is how I am configured: Windows 2000 Server - Standard Windows 2000 and Windows XP Pro Clients SQL Server 2000 MDAC 2.7 or 2.8 on various clients Development Software ----------------------- Delphi 6, update 2 CoreLabs dbExpress driver for SQL Server The error does not occur on Windows 2000 clients, only on Windows XP Pro clients. My application first opens a connection to a server database. Every 2 minutes an application watchdog timer triggers and attempts to write an timestamp value to a data table. After some period of time (seemingly random) the attempted write fails and I get the above error message, followed by a "Connection failure." error. Can anyone point me in the right direction on how to fix this problem?

Also it will much help if you do not expect an open connection to stay connected forever and make new connection after for each triggering of your watchdog.

Bojidar Alexandrov I had the same error - it was the NIC card!!! Thank you Bojidar!!! I used a Dell Optiplex as a temporary platform for MSSQL running Windows 2003. The NIC was onboard. I guess the driver was not right for 2003. Who knows. I changed to my good old 3COM 3c905b tx card, and it is fine. THANKS AGAIN!
