I needed to update my password on my test box the other day. It has DLP 11, and ENS 10.5 on it.
I changed my password and was no longer able to log on to the ePO. It would no longer connect to the database which it shares the same computer. I tested the connection and the connection was good. Test was performed using my udl file on the desktop. No matter what I did, and went around for two days I could not get the connection back. So I re-installed my ePO. Nothing else was removed. The re-install of course made a new Agent package, and I have that ready to go. In fact I have run it, but it is not showing up in my new ePO console.
In order to remove the old Agent and get the new one in and communicating I need to remove all the old DLP and ENS. I try to uninstall via the Add/remove and DLP asks for a removal code, that can not be created as it is not installed and ENS asks for the password. Please note, I never added a password. I wrote all my steps down. I have tried no password, mcafee (as per KB and Prod guide) as well as abcde12345 and nothing. I cannot get either of the DLP or ENS to uninstall so that I can install the new agent.
If there are uninstall tools or tricks, please help. I have been all over the net, all day and have not come up with a means to get these off. And I am unable to wipe my test machine at this time.
After some time and perserverance. I was able to get things back up and operational. I had to forceably remove the Agent that I had originally installed. Then once that was removed I was able to install the new Agent for the new installation. I let that soak for an hour or so and I was communicating back to the new ePO install. From there it was a matter of redownloading the versions of ENS and DLPe i was running prior to the corruption I caused and "bobs" my uncle we are working again.
