Issue at Sonicwall
-
Could be any number of issues. Could be something with their computer, could be DNS, could be the SonicWall, could be a proxy, could be the ISP, could be malware.

@thanksajdotcom said: I am only maintaining the customer site and there is no such above things because last month only ISP provider checked everything in front of me and I am maintaining the Admin console of the Antivirus in that client place.There is no proxy server is used.DNS is also pinged properly from the sonicwall where the ping was successful.

Can you ping Yahoo or MSN or the like? Does it resolve the hostname to an IP?
-
@thanksajdotcom No yahoo.com is not pinging.only the google.com is pinging

Do you have your forwarders setup?
-
Why Gmail works I'm not sure but if your internal works but external doesn't, you don't have forwarders setup, or setup properly.
-
@thanksajdotcom The sonicwall is configured with the load balancer of two ISP.Whether that me any issue?The content filtering is there for the client but the license whether that may the issue.
-
unless the content filter is set to filter everything except google.com that's not your problem.
What is the DNS being used by the PCs, by the servers?
what IPs are set as the forwarder IPs in your Active Directory DNS servers (assuming you're using AD DNS)What happens when you ping those DNS servers from the machine that declares them?

There is no AD is present and the DNS is pinging from server as well as Desktop.DNS is 8.8.8.8 and 4.2.2.2 -

Yes, what is handling your DNS?

If you ping www.yahoo.com or www.microsoft.com, do you get an IP back? and does it ping?
-
Also, just for helpful information, what is the output of
Ipconfig /all
from one of the workstations?
-
@Dashrender The ipconfig /all is used in command prompt and got the IP of
192.168.1.145 Subnet:255.255.255.0 Default Gateway:IP of Sonicwall and DNS:8.8.8.8
Secondary DNS 4.2.2.2 -

ipconfig /flushdnsJust out of curiosity, what browser and OS are you using?
