I thought of documenting it. When a registry key has been modified or corrupted, we strongly suggest rebuilding the whole environment.

Note: Before changing the registry keys, please back up the key.

• Stop sms_site_component_manager and sms_executive service.

• Add a Reg_Multi_SZ value under it. The name should be “Active Order.”
• Double click it, input the value LOCAL MSWNET NWNDS NWBIND
• Open the command line window. Go to the SCCM installation path. It will be under the “\program files (x86)\microsoft configuration manager\bin\i386” folder by default.
• Run following command line: regsvr32 abnwsvr.dll regsvr32 falsvrn.dll regsvr32 mslmsvrn.dll
• After the .dll is successfully registered in the registry, two new values will be generated under the Active Order.
• Then, we will reset the site. Close the SCCM console if it is opened. Go to “Start\All programs\microsoft system center\configuration manager 2007\configmgr setup.”
• When the setup is launched, please choose “Perform site maintenance or reset this site.” NOTE: It is not the default choice; please make sure they choose “here to avoid removing the site by mistake!
• Choose the “Re-apply default file and registry permissions on this site server.”
• Click Next till finish. Then, reset the site.
• After finishing, a new key will be generated. It is called “Connections,” and the value under it is “Operational Active Order.”
