I am publishing several web sites via ISA. The anonymous sites load very quickly for external clients, however the two that require basic authentication are painfully slow to authenticate, and then load, even on subsequent pages. If I remove ISA and use another firewall they load very quickly. Has anyone else experienced this? I am wondering if it is a setting I am missing. Here is a little background: 1. ISA is a domain member, but not a DC. 2. The web server is a stand alone server, with local accounts, so that machine is authenticating for the credentials in question, not the DC's. (should I be using domain specific credentials? I haven't done this because I consider it more security sensitive than just a local user account on the web box which is not a DC) 3. The ISA box hardware is fairly slow, a K62 550Mhz with 384MB RAM, IDE drive. Thanks! Reid Warner
