Authentication issue when user logs on to terminal server 2003
We currenly have an authentication issue which is only affecting 2 terminal server users out of about 30. When the user attempts to log on to terminal server 2003 an error message is displayed stating that the password or username incorrect. Sometimes on the second or third attempt the user is able to log in ok. Other times after 3 failed attempts the user account will lock out and need to be unlocked before attempting to log on again. This can vary from one fail up to 7 or more.
I have looked at the users account settings and them seem to be the same as other users who are not having issues.
Active directory is installed on 2 servers. In active directory Sites and Services under 'servers' there is a total of 3 servers listed. The first 2 have NTDS settings refering to each other which seems to be correct. The third server that is listed in the terminal server which has no NTDS settings attached to it and is not a domain controler. Should the terminal server even be listed here ? If not how would it get there ?. Not sure if this configuration could have somehting to do with the authentication issue.
