Windows 7: "Server Not Found" - intermittent drops in web access

04 Mar 2010   #11

Win7 & XP (very limited Vista)
Mixed OS System... oposite problem

I have about a dozen pcs on a business network with most active pcs on W7 are working fine but all of the XP pcs that actively use browsing are having regular intermittent drop of internet connection and network connection. Release/renew and all is fine for some period of time. The period of time between drops shorten til it gets down to a couple of minutes. Same thing on 1 macbook. Win7 pcs all fine. This mixed invironment worked just fine for 3 months then all of a sudden constant problems. Also have a 7 year old copier/printer with nic that stopped working at the same time. I've been focused on router, firewalls and dns. Seems to me like this is real common globally the past 2-3 weeks. I'm going to get ride of "homegroup" on the one win7 pc that's using it and will turn ipv6 off on all win 7 pcs. Any advise is greatly appreciated.
