With QT recently developed a software, connecting with the mysql server, after the success of the software development, with the root login mysql, the company more than a dozen computers and only a few can access, the rest are not access to state,
Can access the computer no regularity, there are 7 win10, some with 360 some 360
noOn the following measures can not access the computer
1) turn off the firewall, still can't access
2) find the port 3306, has not been occupied
3) to find a computer can't access, reshipment system still can't access
4) transfer QT from mingw compiler to MSVC still can not access

The most bizarre is that some computers can some computers can't, there is no rule to find, and two are the same purchase recently and one can access, one can't, hope to help me move the great god, according to your experience analysis analysis problem is a program or mysql setup, thanks
