I have successfully installed and configured a Windows Server 2008 server as a NAP/NPS server. I have configured it with DHCP enforcement and I have a nap enabled vista client that is working well. I caninstall the SCCM System Health Validator Point Role (SHV) successfully, but once the role is installed the SMS_SYSTEM_HEALTH_VALIDATOR service fails. Ther error is:The ConfigMgr System Health Validator Service failed to initialize properly. The error encountered was HRESULT=0x80040154. Then followed by this error: Faulting application SmsSHV.exe, version 4.0.5931.0, time stamp 0x46c54a18, faulting module SmsSHV.exe, version 4.0.5931.0, time stamp 0x46c54a18, exception code 0xc0000005, fault offset 0x00009e3b, process id 0xdcc, application start time 0x01c821f70c842dba. I have tried uninstalling the role and re-installing but it makes no difference. The SMSSHV.log contains the following error: Failed to cocreate NapServerManagement (0x80040154). Phase 0 initialization failed (0x80040154). Service initialization failed (0x80040154). SMPStateMsg::WriteStateMsg failed. Error Code (0x80070005). Any thoughts? Ross

That error is 'class not registered' Do you have the correct Windows Server components installed and enabled for NAP? (Network Policy Server) This should help: http://technet.microsoft.com/en-us/library/bb632455.aspx

RGangemi, If you check the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NapServer\SHVs, does the Network Services account have full permissions to it? If not, please add those permissions and reinstall the SCCM System Health Validator. Let me know if this does or does not help your problem. Also, which buildof Windows Server 08 are you currently using? That information can be retrieved from the registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\BuildLab Thanks, Michael

I know this thread has been silent for a long time, but I just ran across this same issue (SCCM 2007 R2 on Server 2008 - DHCP server Server 2008). Added NETWORK SERVICE to the SHVs reg key and install went fine afterwards. I also had to add NETWORK SERVICE to a couple of other items to get the NPS role to install on the same DHCP server.Bruce H.

Had the same issue...Resolved using the posted resolution. Network Service account was not in the ACL at all...added it, assigned FC and reinstalled the SCCM SHV role. All installed well after the fix.
