Hi, I am not a security saavy person by any stretch and have run into several situations of late where I can not log into another server using mirrored local accts - seems I am needing to specify the hostname when logging in example: if server A running an application needs to log into server B the credential can no longer be adminacct|password it has to be serverB\adminacct. This happened after upgrading AD to 2008R2 - according to the AD admin this is out of the box and no customization. My question is what exactly causes this behavior? and is there a particular technet paper or description of why it is? Of course I understand the benefits of each server being a domain isolated from other servers, but for applications requiring login credentials it is a major headache. This also affected an install of an application that uses a remote database - a domain account is a workaround but the AD admin certainly doesn't want to be using domain accounts for applications to be able to login as a domain user. Anyway, I have been going through TechNet and just not finding what I am looking for - and not being a security guy it is making it hard to communicate in a way security folks would understand what I am trying to say. Thanks!

Hi muddharrys, What application do you use? How does it log into another server? Please provide more information so we can provide accurate information. Regards, Bruce
