I have problems unable to browse internet because primary DNS was set to active directer server and secondary set to 22.214.171.124
if I change DNS primary to 126.96.36.199 and secondary to AD ip, I will have problems slow windows login, prompt network password when access network folder, login failed when access office report and etc.
For the temporary solution what I do was, when using internet I use 188.8.131.52 as primary when to do office work I swap to AD ip back.
FYI, I have added AD ip and the 184.108.40.206 in the host file.
Is there any permanents solutions or suggestions that experts can help to overcome this problem.
