Windows Deployment Services depends on Active Directory Domain Services for various functions. The Pre-Boot Execution Environment (PXE) provider creates machine accounts and service control points (SCPs) in Active Directory. An SCP is a child object under a Windows Deployment Services server account object, and it is used to store configuration data for the server. For example, an SCP can mark the server as a Windows Deployment Services server so that other Windows Deployment Services servers can find it.

Resolve
Delete a duplicate machine account
Each globally unique identifier (GUID) can have only one machine account in Active Directory Domain Services. To resolve this issue, delete one of the duplicate accounts.
To perform this procedure, you must either be a member of the local Domain Admins group or have been delegated the appropriate authority.
To delete a duplicate account:
- On the server that contains Active Directory Domain Services, open Active Directory Users and Computers.
- Using the GUID that is specified in the event log message, search in Active Directory Users and Computers for the multiple accounts. To do this, you will first need to change the format of the GUID to a format that you can use in a Lightweight Directory Access Protocol (LDAP) query. For information about how to do this, see step 1 in the Workaround section at https://support.microsoft.com/kb/899663. Note: To find the event log message, open Event Viewer. expand Custom Views, expand Server Roles, click Windows Deployment Services, and then find BINLSVC event 519.
- Review the accounts, and select the one you want to keep.
- Delete the other accounts.
Verify
To perform this procedure, you must either be a member of the local Domain Admins group or have been delegated the appropriate authority.
To ensure that there is a service control point (SCP) in Active Directory:
- Open Active Directory Users and Computers. (Click Start, click Administrative Tools, and click Active Directory Users and Computers)
- Browse to the computer account for the Windows Deployment Services server.
- Right-click the server, and then click Properties.
- Ensure that there is a Remote Install tab with the introductory sentence "You can manage this remote installation server." The presence of this tab indicates that there is an SCP for this object.
