Here is my situation: After installing the new Probe and registering successfully to Central OPM, I started the service, and the process hang on which result in the Probe couldn't work as given below My Central OPM and previous Probe are running on v9101, the new Probe I installed is v9101. My new probe is running on win2003 server 32bit and I am sure that the software of v9101 probe is 32bit. I have tried to remove the record from Central OPM and reinstall the new Probe, finally it also hangs on in the DOS. Any idea about it?
