2. Log in with QQ and find that it can go online. , OK;

3, open IE can find the address, but the final display timeout can not be on, halo;

4, re-install TCP /IP protocol, restart (win98), or not, Urgent;

This can make me anxious, what should I do? Only the living horse is a dead horse doctor. Suddenly, I thought of the sfc program in 98. When I ran it, I found that many system files were lost. After I joined, I IE, which is normal. It’s really hard to get it all, it’s too simple. Close-up, for everyone's emergency use.
