SteveC, There was a problem with the Message Screener that was fixed with ISA SP1. You may want to try installing SP1 first if it is not installed, and then try SP2, although you should be able to install SP2 onto ISA 2000 with no other service packs installed. I haven't ran across this error myself, but the fltrsnk1.dll you mention below is used by the Message Screener. To see if you have the Message Screener installed and it is using the Inetinfo process, you can perform the following: 1.. Click Start, point to Settings, and then click Control Panel. 2.. Double-click Add or Remove Programs. 3.. Click Microsoft Internet Security and Acceleration Server, and then click Change. 4.. Click Custom Installation, and then click Add-in services. If the Message Screener check box is selected, it is installed. An then from a command prompt: tlist -m fltrsnk1.dll The output lists the active processes. If the Inetinfo process is listed, the message screener is running in the Inetinfo process. This was taken from KB816621<http://support.microsoft.com/?id=816621>. You might also want to check out KB292013<http://support.microsoft.com/default.aspx?scid=%2Fservicedesks%2Fbin%2Fkbsearch.asp%3FArticle%3D292013>.
