Sorry I cut my original subject of the message ---- Hi all, I have a problem here, i have installed the DSClient on my windows 98 machines, after i´ve installed it, it began to conflict with outlook, and some internet sites, generating ane error on NEGOTIAT.DLL. Searching the microsoft knowledge base, i discover that this conflict occurs when authentication mode is enabled on ISA. Microsoft sad that one way to workaround this problem is disabling this mode (not interested to me) and the other way would be install a new version of the DSClient, BUT, on microsoft website they only had the older version of the DSClient version. So, my question is, has anyone a newer version of the Dsclient??? The year of the creation date of this executable is 2002. Thanks all. Nivaldo Soraggi Fernandes
