Question

VAMT 2.0 and Volume activation services need to maintain access to the Internet?

hellomogen 25

VAMT 2.0 and Volume activation services are two servers respectively, which are used to activate Windows server. Since these two servers can access the Internet for a long time, can these two activation servers disconnect from the Internet? Or open access to designated websites

Hi,

On the VAMT server you can try this URL and Port for direct access only allowing this URL and test it - activation.sls.microsoft.com TCP: 443. Also do a Network trace and see the realtime info on the trace.

Hope this helps. JS

Hi hellomogen, Thanks for your post. In certain scenarios, only a limited set of TCP/IP ports are allowed through a hardware firewall. Administrators must ensure that WMI (which relies on RPC over TCP/IP) is allowed through these types of firewalls. By default, the WMI port is a dynamically allocated random port above 1024. The following Microsoft knowledge article discusses how administrators can limit the range of dynamically allocated ports. Limiting the range of dynamically allocated ports is useful if, for example, the hardware firewall only allows traffic in a certain range of ports. For more info, see How to configure RPC dynamic port allocation to work with firewalls.
