This really isnt my area of expertise...and it may be obvious, but here it is: We have what I guess you could call a virtual network. We have 4 locations in 4 cities connected by broadband internet (Comcast and Verizon) all 5mb business lines. One location houses a file server and a database server for all other locations. This system has been in place since before my time. We have budgeted for a fiber connection in the next couple of years.
The problem is that opening even the smallest files (mostly Office docs) takes forever. Even files that are just kilobytes in size seem to take a very long time to open or even transfer over. Saving changes to a med-sized Excel (or any Office doc)over the network temp freezes up your machine.
What can I use to troubleshoot this problem? ALso, this issue is worse at certain times of the day and particular bad at a certain location. I should also mention that machines located inside the LAN where the servers are stored have no issues at all.
Am I expecting too much by wanting near-lan-like speeds from this setup?
