Zabbix Windows Agent unrechable. Wbadmin, Windows Backup

[pietro54]

Hi evryone,

My problem is that the Windows agent is generating many false alarms when wbadmin process is on.
At start I thing it is case of priority, but no, I change manually zabbix process priority to high and it inset solve the problem.
Interesting is what give me neststat -an from zabbix server:

Probe #1
tcp 0 0 ip.ip.ip.ip:53357 ip.ip.ip.ip:10050
ESTABLISHED

Probe #2
tcp 0 0 ip.ip.ip.ip:60051 ip.ip.ip.ip:10050 ESTABLISHED

Probe #3
<EMPTY>

Probe #4
tcp 0 0 ip.ip.ip.ip:61206 ip.ip.ip.ip:10050 ESTABLISHED

Probe #5
<EMPTY>

Probe #6

Probe #7

On next probes it looks similar...

I changed log level to debug and i don`t see here nothing interesting...

This machine is my AD controller, its double important to have true values from this machine.
Please advice what can be wrong.
I have no ideas for now
