I installed Vista a couple of weeks ago, and I'm having problems with my network connection going down about every10-30 minutes. Usually its down for only 10-20 seconds. If I look at the LAN Connection status, it doesnt notice the drop. However, my applications (SSH, Outlook, IE, Trillian, network drive) lose the connection (although not all of them lose the connection each time). I'm running Vista Business on aDell Dimension 4600 with an Intel Pro/100 VE network adapter. Ive tried updating my network drivers to the Vista version and turning off IPV6, all the sharing/discovery stuff, power management options, etc. Any ideas? Thanks, Frances
