We have 7 sites in town connected by VPN to our main network. They have all been working for months and have given reasonable performance. Last Thursday they all started complaining that it was taking minutes to open Word docs, everything is slow as death, etc. What do I look for?
What baffles me is that I go to a remote site and ping our server, and 90% of the time I get ping times of low 20's (ms), which I think is quite good! During file transfer times, I see pings of say 200 - 300 ms.
Clients are NT - W2K - XP
Each remote site has 1 or 2 PCs, one has 6 PCs
Sites all served by Adelphia cable modem and Cisco PIX 501
Main site Adelphia cable modem and PIX 506
Main network is Win 2000 with 3 Servers, 130 PCs
File access speed on main network is unchanged, and excellent
I don't know of any changes or events coincident with the problem onset.
Appreciate tips on what to look for in diagnosing this.
