I have my LAN Domain, and my DMZ Domain separated via firewall. There is a terminal server in the DMZ, accessible via the Internet, and the LAN. When users in the LAN connect via RDP to the Terminal Server in the DMZ, they must use there user account in the DMZ, as there is no domain trust between LAN and DMZ domains. Users can also map a network drive from there LAN PC's to the server share in the DMZ, again, using there DMZ credentials to connect.
LAN users that connect to the Terminal Server, are consistently finding that their user accounts are locked out. I have other users that use servers in the DMZ domain (Sharepoint), and none of them have this problem. Why are the Terminal Server user accounts being locked out so frequently?
Is it that the users are simply forgetting their passwords, or does it have something to do with the combination of using Remote Desktop, and mapping a network drive to the same server? If a drive is mapped from the LAN to a server in the DMZ, will Windows Explorer try to verify the directory and attempt a logon, each time they open "My Computer" ?
Any ideas or suggestions are appreciated.
