I have 100 computers running Windows XP that still have the 3.6.0 agent. The ePO server errored out while attempting to upgrade and I had to end up reinstalling from scratch. I have installed everything up to the latest version but now I run into errors when I try to push the agent out to the workstations.
I'm currently having 2 main errors pop up when I try to install McAfee Agent 4.0.0:
Failed to authenticate with remote system, system error: the network path was not found Unknown HTTP response received from remote system
I believe this is related to the old agent installed on the computers, however 20 computers have automatically updated to the latest version. I have attempted to remove the agent with the below link (Yoda's instructions), but somehow the old agent stays after I reboot the remote system.
Everything appeared to be good on my end including the firewall on my server and the network. I tried everything under the sun except talk to the head of the firewall team. I spoke to him and we did some further troubleshooting. After much trial and error he noticed that the data appeared to be fine if he watched the ePO server traffic but when he watched the internal network traffic that nothing was getting through.
FIX ACTION: He stated that the 445 Proxy was not functioning properly so he made an IP filter instead and the data was able to pass through.
Thanks for the responses!
