I have tried all of the tricks I know of and that I could find and have not been able to solve a client issue I am having with 2 of the machines on our SCCM 2007 R2 SP2 installation. The client installs fine and appears to be working fine - all of the local logs that are created show no errors EXCEPT for the ClientIDStartup log cannot get past RegTask: Client is pending registration. Sending confirmation request... After a number of tries it errors out to this: Error initializing client registration (0x80040222). The interesting thing about this whole thing is that it is NOT generating a GUID - the SMSCfg.ini file never contains an entry for the Unique ID, so there's no way to REGENERATE a GUID. I've tested MPList communication, uninstalled, CCMCLeaned, Tranguid-ed, ccmdelcert-ed, reinstalled the client using various methods and nothing is able to shake this loose. Any further suggestions would be GREATLY appreciated. This is on an SCCM installation that has been running relatively cleanly for more than a year now.

Hi, I'm having the same problem as the gentleman above, where the GUID is not being generated. I have tried deleting the ConfigMrg certificates locally and restarting the SMS agent host service to no avail. SMSCFG.INI shows the following information only, without the GUID: [Configuration - Client Properties] SMS SMBIOS Serial Number Identifier=530047004800310035003200540042004C005600 SID=S-1-5-21-2395205359-3884802996-287355994 SMS Hardware Identifier 2=00C49902010000FE SMS Hardware Identifier=4CC6990201D600FE Any other suggestions of what I'm missing?? I have the same errors in the logs mentioned above.
