I have a broadband ADSL connection, which is networked through an ethernet connection running through a Dynamode ADSL Router My main computer runs on Windows XP; the second device runs on the (awful) Windows Me and the third on Windows 98 Second Edition. On my XP computer, if my web connection stays idle for awhile (the critical time varies), I become unable to access any site that I have not previously accessed in that session. Using Mozilla, I get a message "unable to resolve host." Using IE, the browser simply cannot find the site. I had thought the problem might lie with my ISP, but oddly I NEVER have this problem with the Windows Me or Windows 98 machine. I've read one article that suggests the problem is XP caching unsuccessful DNS lookups, but the solution suggested in the article did not cure my problem. (See http://cable-dsl.home.att.net/dns_cache.htm) Any suggestions?
