Provisioning a Windows distribution to a managed server can fail for several reasons:
The Windows operating system might not be compatible with the managed server. For a list of qualified servers, see Manageable Server Requirements in Sun N1 System Manager 1.3 Site Preparation Guide.
The SSH entries for that managed server on the management server known_hosts file might be stale or obsolete. Determine the management server name and IP address, and then remove the entry for that managed server from the known_hosts as described in To Update the ssh_known_hosts File.
The product key is unique to each release of the Windows OS. To ensure that the correct product key applies, either modify the OS profile to include the correct product key or use the productkey attribute on the load server command.
If you encounter a TFTP error when loading the OS profile, the GUID is likely incorrect. To find the GUID of a system, use the Pre-Boot eXecution Environment (PXE) to boot the system.
If Linux was installed previously on the managed server, Windows will ask about partitions the first time that you try to install Windows on the system. To resolve this issue, delete the partitions on the console, or wipe out the first part of the disk before you install Windows.
