I tried logging off and logging in as a different user but get the same results. I tried safe mode, last known good configuration with same results. If I boot in safe mode with a command prompt, then I get a cmd window and can run some programs (regedit for example) from that window. But still, cannot start a new task from the task manager (same error as above). I tried running SFC from the command prompt but won't run (error: The RPC server is unavailable).
I tried remaning the user profile and logging back in but still have the same problem.
I will appreciate any help.
