We've got a WX1-0TL-R1. We have successfully joined it to an AD domain which is in Windows 2000 mixed mode. on the Terastation under Users/Groups in the Domain Users and Domain Groups, the entries keep disappearing and mapped drives to the TS from local computers stop working at that point. If I use the Web interface on the TS and go to Network - Workgroup/domain, Modify the settings and re-enter the administrator account and password we use for the Domain, the users and groups reappear and the mapped drives start working. Anyone got a fix for this? times are within 1 minute, AD account we use is a special domain admin account we created for the purpose, DNS works, Domain Controller is the DNS server. Firmware is version 1.5
