记一次菜鸡解决Win7 DNS问题

    选择打赏方式

症状:

某天电脑突然域名解析失效

nslookup 可以解析

ping IP ok

ping localhost 解析错误

ping 主机名 解析错误

ping 127.0.0.1 OK

ping 域名 解析错误

Chrome 访问IP站 OK

Chrome 访问域名站 解析错误

Chrome 挂代理访问域名 Ok

-----------------------------------

试图修复:

..1..网络原因?

确认内网其他终端正常

修改路由器DNS并重启  无法解决

..2..配置原因?

修改系统DNS为手动 无法解决

查看hosts文件...    无相关

netsh winsock reset 无法解决

重启DNS Client服务  无法解决

360断网修复  无法解决

下载火绒完全版

火绒断网修复 无法解决

-----------------------------------

..3..需要更新?

更新系统补丁 无法解决

..4..中毒了?

360查杀 无法解决

火绒查杀,userinit被修改?重置后无法解决

..5..核心的内容被篡改了?

打开火绒-火绒剑

...瞅瞅启动项-服务-内核,瞅不出来0.0

打开系统-开启监控

使用ping www.baidu.com测试

关闭监控

看看有没有调用奇怪的东西

banjour、ludashi ????

0.0不知道有啥关系,卸载apple banjour

直接删C:\Users\Administrator\AppData\Roaming\ludashi

话说LDS真的狗,重启后软用没有

-------------------------------------------------

PING.EXE相关调用里看到这三个dll...有关

KernelBase.dll
ws2_32.dll
kernel32.dll
注册表

WinSock2里Protocol_Catalog9、NameSpace_Catalog5看起来奇奇怪怪

先备份[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\WinSock2

NameSpace_Catalog5\Catalog_Entries

我这里网上说可以调整到3..又是一顿乱尝试,,没软用

-----------------------------------------------

重启进入机械硬盘的旧系统,可以联网

对比KernelBase.dll、ws2_32.dll、kernel32.dll,大小日期不一样

将上面三个dll,system32和sysWOW64里替换了

顺便同样备份了Winsocks2的

重启后同样没软用

----------------------------------------------

尝试将旧系统注册表内容覆盖进去

???解决了。。。???

所以是为啥。。

——————————————————

Beyond Compare对比了下

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\WinSock2\Parameters\NameSpace_Catalog5\Catalog_Entries\000000000005]

"Enabled"=dword:00000000 换成了00000001

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\WinSock2\Parameters\NameSpace_Catalog5\Catalog_Entries64\000000000005]

"Enabled"=dword:00000000 换成了00000001

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\WinSock2\Parameters\Protocol_Catalog9]
"Next_Catalog_Entry_ID"=dword:00000196 换成了000003ff
"Num_Catalog_Entries"=dword:0000000a 换成了0000000e
"Serial_Access_Num"=dword:00000008 换成了0000004b
"Num_Catalog_Entries64"=dword:0000000a 换成了0000000e

对比下10和14区别


10里面
%SystemRoot%\system32\mswsock.dll
@%SystemRoot%\System32\wshqos.dll,-103

14里面
C:\Windows\SysWOW64\ierd_tgp_lsp64.dll
ierd_tgp_lsp64P/IP]2\wshtcpip.dll,-60100

复现上面值改成10就同样问题,所以还是LSP的问题

难道又是WeGame的锅?所以???


下次这样重装或删除WeGame应该就行,TMD
