To be more clear - Russ, I don't see ISAHF55.exe listed as an available d/l. Is in now included in SP2 for Win2k? Is there a separate SP for ISA? I haven't found one... I am looking here: http://www.microsoft.com/isaserver/downloads/default.asp Thanks, Andrew -----Original Message----- From: Andrew Dadmun [mailto:adadmun@xxxxxxxxxxxxx] OK After more reading, it seems that I should be able to re-apply Win2K SP2 and it's hot fixes. Then I apply the ISAHF63.exe and ISAHF68.exe. Does that seem correct? IF that doesn't solve the problem, then I call PSS and get the replacement BWSERVER.DLL. Comments? Andrew
