|I work with a non-profit health clinic system and have been experiencing an incredible amount of issues with our network. We have one central location where we have all our local servers. We also have 4 remote site locations each with their own primary file server which connects back to our corporate ones through our MPLS network. The remote sites use RDP sessions to login to our medical software which is hosted and running on a server at our central location.|
The issue we are having is that the network connection from our central server to the site servers is extremely inconsistent. When we ping our remote servers from our local servers (or vice versa) the packets vary dramatically from ~15ms to 140ms, to losing packets entirely, then returning to somewhere in between. The clinic at our central location does not suffer from this slow down, but it also only traverses our switches and does not go through our router or MPLS network. This leads to a very frustrating issue with our remote clinics where the program will run ok one minute, be extremely slow the next, and then appear unresponsive.
I am unsure if there is some setting on our routers that would need to be changed... or something else entirely. We've already tried disabling Large Send Offloads and IPv6 on our NICs. When we check the network usage on our primary server, it is never more than 3%. Similarly both the CPU and Memory have all been satisfactory as well.
We have been working on this issue for the past week and haven't been able to come up with a solution. Any help or suggestions would be greatly appreciated.
