SMS Distribution Manager failed to initialize the network abstraction layer (NAL)

I had this problem on SCCM 2007 SP2 R3 installed on Windows Server 2008 R2 SP1.

To fix this annoying issue is necessary to rebuid the NAL: 

Rebuild NAL:

1. Stop sms_site_component_manager and sms_executive service.

2. New a registry key: HKLM\software\wow6432node\microsoft\Nal\server\providers

3. Add a Reg_Multi_SZ value under it. The name should be “Active Order

4. Double click it, input the value

5. Open comman
d line window. Go to the SCCM installation path. By default it will under “\program files (x86)\microsoft configuration manager\bin\i386” folder.

6. Run following command line:

regsvr32 abnwsvr.dll
regsvr32 falsvrn.dll
regsvr32 mslmsvrn.dll

7. After all the .dll is registry successfully, there will be 2 new value generated under the Active Order.

8. Then we will do a site reset. Close the SCCM console if it is opened. Go to “Start\All programs\microsoft system center\configuration manager 2007\configmgr setup

9. When the setup is launched, please choose “Perform site maintenance or reset this site”.

NOTE: It is not default choice, please make sure the choose of “” here to avoid remove the site by mistake!

10. Choose the “Re-apply default file and registry permissions on this site server

11. Click Next till finish. Then reset the site is doing.

12. After finish, there will be a new key generated. It called “Connections”, there is a value under it, it is “Operational Active Order”.


13. After that, the NAL seems rebuild. Restart the server, then your Distribution Point will be working fine.
