We have installed the ASA [Cisco Adaptive Security Appliance Software Version 8.4(7)3 --Device Manager Version 6.4(5) ] in our Data Center. All our branch offices are connected to the Data Center via MPLS network.
Whenever the Clients browse the "go.microsoft.com" webpage, it doesn't load the webpage. It displays
1- Unable to access the network [ERR_NETWORK_ACCESS_DENIED] in Chrome
2- This page can't be displayed in Internet Explorer.
But, when I browse the same webpage by bypassing the ASA, it loads the webpage successfully.
To further troubleshoot the issue, I captured the Data packets using the Wireshark program. I found that the client requesting the webpage "go.microsoft.com" [resolved to IP 23.64.230198] , I see the RST ACK packets from the website.
This issue affects the Microsoft Products activation like "Windows 7" and "Office 2010". I see the same RST, ACK packets received while activating the Microsoft products. But there is no issue while activating the "Windows 8" and "Office 2013".
