in the MP_ManagerRegistration.log i found this message: Certificate issued to 'SMS' has expired.MP_RegistrationManager18.04.2008 10:49:3327952 (0x6D30)MP Reg: Registration request body is invalid.MP_RegistrationManager18.04.2008 10:49:3327952 (0x6D30)MP Reg: Registration failed.MP_RegistrationManager18.04.2008 10:49:3327952 (0x6D30)MP Reg: Processing completed. Completion state = 0MP_RegistrationManager18.04.2008 10:49:3327952 (0x6D30) maybe this is the problem why my clients do not rgister. I have SCCM SP1 / R2 Beta on this server. Anyway any ideas to solve this problem ? thx oliver

sorry for not updating this topic but i solved that problem by my self. In this case the certificate from my MP was not valid. regards Oliver

I was trying to install a client on a system that appeared to have an old non-functioning SCCM 2007 client installed. I uninstalled and reinstalled the client and got very few CCM log files and the "RegTask: Server rejected registration request: 3" error in clientIDManagerStartup.log appeared almost instantly. I figured it may be a GUID issue due to the previous client install and followed the directions here to clean it up: http://blogs.technet.com/b/csloyan/archive/2010/04/27/system-center-configuration-manager-and-duplicate-guid-s.aspx In case that site is inaccessible: 1) Identify the systems with a duplicate GUID 2) Delete the c:\windows\smscfg.ini file from the client 3) Run CCMDELCERT on the client (*) 4) Restart the SMS Client agent (SMS Agent Host) 5) A new GUID will be generated (*)Ccmdelcert.exe wasn't included in the System Center Configuration Manager 2007 Toolkit, but you can still use the version in the SMS2003 Toolkit 2. You can download that here: http://technet.microsoft.com/en-us/sms/bb676787.aspx It took about 30 seconds after restarting the SMS client that all of the log files started to populate and the client registered successfully.
