I have been using ISA for a while now and it has been working fine. The problem I have is that in the log files where I used to have some entries as anonymous and others with their correct name I now get mostly anonymous username with just an ip address and very few username entries. Can someone tell me what is going on so that I can fix this? 10.0.2.106 MPI\ColetteT Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0) 10.0.2.106 anonymous Mozilla/4.0 (compatible; MSIE 4.01; Windows NT) Thanks Joe
