Hey aavsec, What Claus probably means are the client msi parameters used to install the SCCM client. Take a look here http://technet.microsoft.com/en-us/library/bb680980.aspx Moiz

SMSSLP should only be HOSTNAME, it is WINS so it isn't a FQDN... Is the SMSSLP set up in WINS as shown here - http://technet.microsoft.com/en-us/library/bb694195.aspxMy Microsoft Core Infrastructure & Systems Management blog - blog.danovich.com.au

Hello, I am having troubles running SCCM agent on machine. I am installing it manually. The installation is successfull, but once the SCCM agent starts, there are many errors. If i use SCCM to push the agent to this client, then it installs correctly and it runs correctly. If I install the client manually on a machine in the same forest as the site server then it runs correctly. I am using the following configuration Server : SCCM 2007 R3 SP1 Native mode Forest A Client Windows Server 2008 R2 SP1 Forest B The certicates are correctly configured. The client seems to be correctly assigned. The parametres used to install the client manually are the following : ccmsetup.exe SMSSITECODE=AUTO SMSSLP=SP01SCCM.domain.fr FSP=SP01SCCM.domain.fr Here are the errors that I encounter in the different log files on the client: Ccmexec.log [CCMHTTP] HTTP ERROR: URL=http://SP01SCCM.domain.fr/ccm_system_windowsauth/request, Port=80, Protocol=http, SSLOptions=0, Code=0, Text=CCM_E_BAD_HTTP_STATUS_CODE HandleRemoteSyncSend failed (0x80040231). CForwarder_Sync::Send failed (0x80040231). CForwarder_Base::Send failed (0x80040231). ClientIDManagerStartup.log RegTask: Client is not registered. Sending registration request... RegTask: Failed to send registration request message. Error: 0x80040231 RegTask: Failed to send registration request. Error: 0x80040231 Please find a zip containing the client log files at the url: http://www.mediafire.com/?sprfh6z05hbd46g Best regards, AntoineAntoine

Pretty sure it's an install parameter issue. Please paste in errors from ccmsetup.log

Hello Claus, The client installs successfully, I have no error in the ccmsetup.log file.Antoine
