i have similar problem as http://dynamicsuser.net/forums/p/31981/167748.aspx but only different is I can access the NAV company with classic client but not with RTC. i get the error message “The User ID and Password are Invalid. Try Again”
I have win2003 server which has Sql 2008 and Nav 2009 on it. There is no Domain and all clients and server are on workgroup. i get this error message from the win2003 server.
