Problem with some users internet access??
Were having some problems with some users internet access, one day their internet access is fine and working and then a few days later it just stops working then a few days later it starts to work again.
This is driving me mad as we cant seem to replicated the problem once the users internet access starts to work again. We use the sophos WS1000 web filters/proxy and microsoft ISA. both devices say that the users have access to the internet with no problems but when the users try to go online all they get is the page cannot be displayed.
All users get the same proxy details applied from active directory so if there was a problem with the proxy details all users should stop working, does anybody have any ideas????
Thanks in advance
