I believe many people have encountered this problem, obviously can log QQ, but the page is not open, and this is often the case with the card icon display cases exclamation mark. Here I teach you a way to ensure ease of use.
First, in the start menu type cmd, and right-click in the command mode character select "Run as administrator."
1. Type ipconfig / displaydns enter, pay attention to leave a space after ipconfig, then look at the cached DNS resolution server address is not a lot? These are computer ever used dns cache oh, sometimes, DNS failure can cause problems Noto QQ can not access (the role of DNS is to translate IP addresses - URLs).
2. Then, enter ipconfig / flushdns Enter (note the space), empty the DNS, the Internet can give it a try - in fact, this step is to empty the cache, the system will re / operator requests DNS server is automatically assigned to the higher routes. Xiao Bian here also recommended two DNS, such as 114.114.114.114 (telecommunications DNS) and 223.5.5.5/223.6.6.6 (Ali DNS), can be set manually on the adapter card's advanced options.
3. If you still can not find the page log in, please come to a command, enter netsh winsock reset Enter this command to re-initialize the network environment, including IP address, DNS, network cards, and so on. Note that after the netsh winsock reset input is complete, you must reboot the computer.
