I manage a small LAN of about 30 users in my organization. We also have about 40 users who use Remote Desktop Connections to access an application on one of our servers from remote locations. We have a separate server for Exchange, and one for SQL Server which hosts the shared application. Over the past week or so, I have noticed, as have many of the LAN users, a definite slowdown in the response time of network operations, for things like accessing the Internet, as well as accessing local server files. People in remote locations have not reported any problems. Can you recommend a good utility to try to analyze where this slowdown is coming from, or some other tests I can run to try to isolate the problem? I'm not sure where to start with this, as nothing has changed lately that I can point to. Thanks.
