We have 2 ISA 2006 Servers running with an Array. We also have Caching set to local drives for each one. Once a week it seems that certain Internet sites are being redirected wrong, slowness occurs, or pages can not be viewed. When I stop the services on server #2, delete the cache, restart services, then everything is fine until a week or so later. Anyone have an idea what needs to be done. It does seem that one server is the culprit. Thx...
