and SCCM client repair didn't help to fix you client communication.

You can try to do these to fix it, 1.Stop SMS Agent Host Service 2.Delete C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys\19c5cf9c7b5dc9de3e548adb70398402_50e417e0-e461-474b-96e2-077b80325612 3.Start SMS Host Agent Service and monitor the log file ClientIDManagerStartup.log  ! : New 19c.... certificate file should also have created automatically in the folder above.

You should be able to see informational log entries if it helped, like

No SMBIOS Changed ClientIDManagerStartup 04/12/2013 11:33:29 2212 (0x08A4)  ....

If you are still seeing same errors, you can also try to change permissions of C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys by adding Local System.

Ps. The cert. path in XP systems is C:\Documents and Settings\all users\ApplicationData\Microsoft\Crypto\RSA\MachineKeys\
