I have a network of 5 Macs running OSX and 5 Windows 7 machines. We also have 10 printers on the network. This runs through 2 switches and a Linksys router hooked up to our cable connection.
The problem we notice frequently is that our Windows 7 machine that we use to get files off the Macs seems to frequently lose its connection to them for a minute or so then it gets it back. During that time though the internet works fine on both the machines.
Any advice on troubleshooting this or where to look?
We have a network drive that stores our files but we frequently have in progress work that is created on the Macs and then pulled up on our Windows 7 machine for different reasons. That is when the problem rears its head. The Windows 7 machine seems to lose all local computer access even other Windows machines. The machine in question was also recently upgraded with a new MB and CPU so I doubt it is a hardware issue.
It seems to happen randomly, but generally during an 8 hour day it will happen 4-6 times.
See if you can narrow down the times. Also, make sure you have all power management settings to off, especially for the network card. They are often set to allow the computer to shut it off to save power. It's usually in the options of the network card as well as in the power settings in Windows.
