Had phone system upgraded recently where I work. Router and phones where installed and right away half the computers where unable to connect to the server and the network printer is completely inaccessible.
All computers have new IP addresses now and only some of them are able to connect toe the server. The IP address for the printer times out when I try to ping it and it is the same for the old IP address of the server. These settings where not changed when phones where installed. The server still lists the old IP address on old ethernet port but now has a new ethernet port with new IP address that is being used by the working computers. Disabling this new ethernet port disables all access to the server.
Trying to map the network drive with some computers does not work and says that the folder is not valid on windows xp or that windows can not access the folder on windows 10. On the working computers I can map the network drive normally with identical commands.
