Hi,

I have problems unable to browse internet because primary DNS was set to active directer server and secondary set to 8.8.8.8

 

if I change DNS primary to 8.8.8.8 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 8.8.8.8 as primary when to do office work I swap to AD ip back.

 

FYI, I have added AD ip and the 8.8.8.8 in the host file.

 

Is there any permanents solutions or suggestions that experts can help to overcome this problem.

 

Thanks

Not able to set DNS settings to automatic because the button is in grey. if I set IP address to automatic, I can set DNS to automatic but it become worse can use internet and office work.

Right, from the sounds of things somethings up with DHCP/DNS then. Does everybody in your office experience this issue, or is it isolated to yourself? I'm assuming you're the IT tech for your office, do you have admin access to the servers?

What is the DNS pointing at on the DNS servers? I'd suggest setting them to your ISPs or OpenDNS's IP addresses. 208.67.222.222 and 208.67.220.220

 

Then set the DNS on your machine to the IP of your DNS server and let me know how it goes.

We did not have DNS server, we set DNS manually at the modem.

 

FYI, our ISP came in and check modem yesterday and did change the DNS settings to 8.8.8.8 , 8.8.4.4 , 1.9.1.9 (ISP DNS) and advise to monitor.

 

Hope it resolve the problem. If you have other suggestion and I open to test it.

 

Thanks.
