Have anyone seen an issue where Windows 98 machines that try to get into OWA for Exchange 2000 are only prompted the first time they go to the site for username and password. Subsequent times to the site they are auto logged on with the previous users credentials. The only way to get a logon screen to come back up is to reboot the PC. I have deletes temp internet files, cookies and set IE to not cache anything. Anybody seen this issue and know a solution? --------------------------------- Do you Yahoo!? Yahoo!
