Microsoft OLE DB Provider for ODBC Drivers error '80004005' [Microsoft][ODBC SQL Server Driver]Communication link failure 根据错误提示判断，是因为你长时间没有访问数据库，导致和服务器的连接断掉了。为了防止这种情况，你应该在程序空闲是利用一些没有的指令来保持与数据库的连接，或者发生错误时，关掉连接然后重新连接。Reply: it's been my experience that this error means the network connection between the client and server was lost. basically your LAN went down - the server kept on running, but your app couldn't use the network to talk to it.Just I want to raise this question. O.K I had some views on this. This is mainly due to the netwotk problem . Due to heavy trafic.In your question U didn't mention about how u use this. Remote access. Are using Lan,Or single system If its lan check your Lan connection properly and try to establish the connection in the error.
