We have just recently added two new servers to our PS 4.0 farm (Win2k3). During the setup we set the registry defaultdomainname setting (HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon). However, every time the server reboots (we set the reboot schedule to once per week) this registry setting is removed (left blank). Using Microsoft's RSoP tool I cannot see any GPO that would be removing this setting. We even tried creating an .adm file to assign to the local security policy that will set the Default Domain Name but that only works when we run it manually (GPUPDATE /Force), it doesn't appear to be applied when the server reboots. Has anyone see this problem or have any ideas how I might be able to troubleshoot it? thank you in advance. Jim
