I'm a sysadmin for an office in a company in Ireland. We have another office in the US. Some of my users access files on file servers in this US office over the WAN using a secure MPLS VPN connection. Everything is in the same domain so we just have to map a network drive to the US server.
I'm getting reports that accessing files over the WAN to this US server are poor, taking ages to read/write etc.
Is there a tool I can use to monitor the connection to this US server and guage whether there is a bottle neck along the WAN be it at the network layer or across the Internet?
I would add I'm not the most experienced with Cisco devices.
Any advise would be welcome.
