The current setup we run is Zen 10 with Windows 2003 servers. Recently we have been getting alot of double logon issues. What happens is When you logon it will act like it going thru, then it will prompt you a second time to logon again. At this point if you put in the password it says "Unable to log into the network because the login credentials or the server certificate is incorrect." Does anyone have a fix for this yet? Please help..Thank you.
