implementing the last Cisco VoIP solution for our offices, I’ve stumbled across
a problem with machines (all Windows) that occasionally drop their network
connection just briefly every couple of hours. While this normally
wouldn’t be a problem, it is for us because we redirect several of the default
Windows folders to a Windows server. When the connection drops, Windows
loses these folders and you have to log off/log on to get them back.<o:p></o:p></p>
