Agent2 on Windows server - unsupported windows service command recieved

[Gert Vanderstukken]

Hello all,

I have been using Zabbix in the past (version 1.6, 1.8, ... 2.4 era ) and now picking up again.

We installed zabbix 5.2 and I have to say: I am impresses with the improvements. I really like my comeback...


Anyway, I tried using the agent2 on Windows systems (Microsoft Windows Server 2019 Standard) and ran into the following issue.
The logfile is filling up with messages like:

2020/12/08 21:19:19.210982 unsupported windows service command recieved

This is even after installing an agent on a server that does not yet have a host defined in zabbix => no items.

Is this a known issue? Or is nobody using agent2 on Windows?

We have noticed the same thing, the older (non version 2 agent) appears to work ok !

Also have same problem on WinServ2019 with Agent2

I face a same issue on Win Server 2019 and Zabbix Agent 2. Did you find any solution?

I also have this problem. Agent version is 5.0.5. I will update the agent to 5.0.7 to see if that helps and report back.

I am sure to fix this we remove and re-loaded the client. However we only installed the agent not the proxy, ours are signing in to a Zabbox proxy, so both the server and proxy addresses are the same, and its set to active, then the errors stopped

I thought upgrading to agent 5.0.7 may have fixed this problem but it appears it has not. I also see in my agent log file "cannot process incoming connections: EOF". Not sure if this is related or not. Also, the agent that is reporting these errors is not able to startup when the host has boot up. I have to manually start the service which seems to work but obviously isn't correct. Anyone else see the "cannot process incoming connections: EOF" errors before?

FYI: We are having the same issue with Zabbix2 agent and thinking of moving back to zabbix V1 agent. Not sure if it's related but also have multiple agent Windows Services stopping periodicially

Same issues. Server 5.0.9, agent 5.0.10.
