Consult everybody warrior, I met a strange phenomenon, we have a client (operating system is xp) program is a c # development, needs to connect the background of essentially a server database (server operating system is xp), source directly connect to the database is written in the death of the server machine name and database name and password, has been used very well, before connection is also very normal, but recently the client's operating system is out of order, we do the xp system (and xp version is not the same as before), and then run the program wasn't on the original database backend server connection, but the connection another Windows 7 system standby server is normal, the name of the machine can also ping ping server, and enable the spare the client computer (xp) connect the backend server is normal, this is how to return a responsibility
