I have a Hyper V Virtual Server that is about 3 years old. Using it for Exchange. We recently went to Office 365 but kept the server as a on-premises server. I reduced the memory size on the server as I was adding more virtual servers to the main server. For some reason, I am unable to ping any other device outside of the current Lan. We have several off site locations which connect to this site and now I am unable to ping any outside site from this server. This was just noticed today. The memory change was over a week ago. Can anyone help?
