Hello, We have a network, all with NT4 sp6 and SBS on the server with proxy 2.0, and are having some problems opening webpages on the workstations. At some time we are unable to open some pages -others open without any problem- on our workstations (they make no direct connection to the internet but connect trough the proxy. When we try so, we even receive the announcement "page under construction". First I tought I was the provider, but this can't be as we can open these pages at the same time without any problems on the server! The next day it is possible that we have no problems... I was adviced to clear the cache pages each time; but this doesn't work either. Can some help me? Is it some setting in the proxy server? Thanks.
