Another question related to Samba 4 as an Active Directory DC (with other Windows DCs present). I'll mention that I am using rsync to synchornize the sysvol share between the Windows-based DCs and the Linux-based DCs, so the GPO objects should be consistent across all of the DCs. When I try to do a "gpupdate" on my Windows 7 Pro/Enterprise clients, I am frequently receiving the following message: "The processing of Group Policy failed. Windows could not determine if the user and computer accounts are in the same forest. Ensure the user domain name matches the name of a trusted domain that resides in the same forest as the computer account." Anyone know why this is happening, or where I should start debugging? I'm not sure why it's having trouble matching computer and user domains, since the computer is in the domain, I can successfully authenticate to the domain, and can attach to other computers in the domain. Any pointers/help in tracking down the problem would be greatly appreciated. Thanks, Nick -------- This e-mail may contain SEAKR Engineering (SEAKR) Confidential and Proprietary Information.
