The weird problem which I posted long time back still exist. ISA server configured for server publishing just stops working. No error in the event viewer. Restarting the firewall service resolves the issue. At the time of the problem I can connect to the internal web server from the ISA box itself by specifying the ip of web server. So something happens that request from outside doesn't go through. any suggestions? Thanks Shobha Pandey Network Operating Systems OIS Bureau of Technology Department of Public Welfare 717 772 7204
