Hello All I have installed ISA on Win 2k with all the necessary hotfixes. I have also defined site and content rules to block ads, sites, and downloads for a certain period. Since last few days, I have been observing a problem that the clients are complaining that firewall client shows inaccessible after some time. When i turn off all the site and content rules, it works fine. Can anyone tell me what is the problem and how it can be resolved. Thanx
