Problem: The error message shown in Figure 3 is displayed when you attempt to create a Configuration Manager PXE service point using the Create self-signed PXE certificate option.
Figure 3. PXE service point error
Possible Solution: If a PXE service point previously existed on the server you are configuring, the PXE service point may not have deleted the self-created certificates when you uninstalled it. Delete the PXE certificate folder from C:\Documents and Settings\user_name\Application Data\Microsoft\Crypto\RSA, where user_name is the name of the user performing the current configuration or who performed the previous configuration. The New Site Role Wizard in the Configuration Manager console should successfully finish when you have deleted the folder.
