Good afternoon friends, I live in Brazil and I am translating this text, sorry if something goes wrong. I have about 400 computers with windows xp, since last week, some computers are giving problem (we own a corporate license). I am unable to figure out what the problem is, every time appears on a different computer, all they have kaspersky endpoint 10 and have no virus alerts. The internet stops responding, the programs are extremely slow and some fail to Respond. When I restart the computer, everything is standard for some time and happen again. These are computers with the updates made. I have the vnc program on these computers and when this problem happens I can not connect to them by VNC, the error is that the CONNECTION ended. This above error, the computer has network but what appears is that the VNC service stops responding. I sincerely fear that this is something of microsoft to own forces to be replaced windows xp for something newer. I know I'm at risk with this system, but the reality is that computers are weaker and windows xp is well so far. I'm waiting for any information that may help me.
