Cool beans-does that mean it works? I've actually never been skiing... unless the Wii counts, and I'm still not good at it... just snowmobiling where I dare =)

Okay, you might try this trick, which I've been keeping up my sleeve in case I ever needed it. Although the reference is to clustering, in theory it should work with any system though. I have not tested it at all, so if you decide to try, let us know if it works! found in http://technet.microsoft.com/en-us/library/cc720067.aspx "RIS Remote Installation Services cannot be used unless certain prerequisites are present, such as a dedicated private cluster network and a valid RIS image with a valid license key (PID). For a list of RIS prerequisites, see Installing Remote Installation Services<http://technet.microsoft.com/en-us/library/dca48e0a-6bf9-45b6-af2f-04221d607f00>. RIS fails when adding compute nodes because servers have duplicate GUIDs. A GUID is a 128-bit integer (16 bytes) used by Microsoft operating systems that can be used across all computers and networks wherever a unique identifier is required. Such an identifier has a very low probability of being duplicated. Every computer is usually assigned a unique GUID by the original equipment manufacturer (OEM). However, in rare cases, OEMs assign the same GUID to multiple computers. When compute nodes have duplicate GUIDs, the Automated Addition method of adding nodes will fail. This failure occurs because Remote Installation Services (RIS) uses the node's GUID when creating a new computer account in Active Directory. If any compute nodes have duplicate GUIDs, RIS will not be able to create unique computer accounts in Active Directory for each compute node. As a result, automated installation will fail. * Contact the OEM and obtain a BIOS update for each computer involved. * Edit the registry on the head node, placing the duplicated GUID on the Banned GUID list. The computer GUID can be seen in the PXE boot phase of computer startup. If you find duplicate GUIDs among the computers that you intend to use as nodes, access the head node and edit the registry. Add the duplicated GUID to a registry key named BannedGuids located under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\BINLSVC\Parameters. [cid:image001.gif@01C917F5.49A6E2F0]Note Modification of this registry setting (i.e. the addition of a Banned GUID) must be accomplished while the RIS service running on the head node is stopped (running net stop binlsvc from a command window) and the Compute Cluster Administrator Console snap-in is closed. Once the modification is made, the Compute Cluster Administrator Console snap-in can be opened again and automated deployments of compute nodes initiated. If any of the GUIDs in the Banned GUID list are detected during PXE boot, RIS automatically uses the MAC address of the private network adaptor with the last 12 digits of the GUID. This creates a unique identifier for each computer. RIS then creates the computer account in Active Directory using this identifier, which solves the duplicate GUID problem. " -Bonnie From: Joseph L.

Sigh :) jlc From: Miller Bonnie L. [mailto:[EMAIL PROTECTED] Sent: Tuesday, September 16, 2008 9:30 AM To: NT System Admin Issues Subject: RE: RIS, GUIDs and Cheap Mobos I know our Dell boxes create the GUID based on the Asset number, which is stamped into the MB's firmware. If we get a refurb or replacement for any reason, we have to run the asset utility to embed the number or end up with duplicates. Do your mobo's have any options to create a unique asset or serial number that the BIOS stores? -Bonnie From: Joseph L.
