Disappearing Domain Accounts when adding Domain Account as Local Administrators

Story – Creating a new local lab environment using VMware Workstation for Guest OS Windows Server 2008 R2 with SP1.

I created a Domain Controller SERVER-A and created some domain service accounts (svc-A) that were to be used as Administrators on member servers.

After attaching a new guest SERVER-B as a domain computer, I tried adding the svc-A account under the local administrators group. It would let me add the account, but as soon as I added (and applied), the svc-A account would disappear from the local Administrators group.


So I try to add that account again – and – error – “Account svc-A is already a member of this group”

Culprit – my sysprep process. For Windows Server 2008 R2, I did not check the “Generalize” option, and that would not create a new SID for the member server.

I had to check the “Generalize” option, which then creates a new SID, which then allows me to add and view a domain account under local administrators for that member server.

Optimize your Virtual Server VHD

I have extensively used Microsoft Virtual Server 2005 (graduted to it from Virtual PC) for testing, evaluating and other tasks. In order to test a new product/software I always start off with a clean Microsoft Windows Server 2003 SP1 (Guest OS).

Prepare a clean Windows Server 2003 Sp1 image that you can reuse. Sysprep it and save it. That way new SID’s will be generated everytime you “create” a new guest OS. It is crucial that this base image be optimized for size as well.

These are some tips on optimizing for Virtual PC which can be applied to Virtual Server as well.

* How to prepare a Virtual Server 2005 virtual hard disk file

After following all the detailed steps, reading the guidelines, precompacting, inspecting and Compacting virtual hard disk my original Guest OS image (Windows 2003 Server SP1 + Microsoft Office Professional + IIS) size was reduced to 2978718208 bytes from 4814174208 bytes (approx 40%), took about 3 hours. My Guest OS images are on an external USB disk. If you dont have 2 seperate disks I highly reccommend getting an USB disk for all your images so that the Host OS and Guest OS dont compete on your system.
