Intranet Site Stops Working On All Browsers

[ashishgupta6]

Hey Guys,

I am dealing with a very strange issue. What actually happens, All intranet websites work fine without any problem but after 15 - 20 minutes all of them stops working one by one. With my mac, I am able to ping their server and traceroute also works fine. Everything seems fine but not able to open the website on any browser.

Note: I make it working by only one way, turned off the WiFi and turned it on again. It solves my problem but for more 15-20 minutes. This problem is with only internal (Intranet) websites.

Please help me to find a solution for it.

Thanks,
Ashish

When you "ping their server" - do you ping IP address or DNS name?

If you ping IP address - try FQDN instead. Will help you determine if it's a DNS issue.

@jcompton Thanks for your inputs. But it is not the DNS issue. Name resolution for these websites is working fine, even FQDN is also working fine. As I said before, it works for some time without any problem and then all of sudden it stops working.

@ashishgupta6 is Sophos deployed to those Macs?

If so, disable Web protection.

@bentoms We are not using Sophos. We used to have Symantec Endpoint Protection and now we are using System Center Endpoint Protection.
