I'm using ActionShellExec option in the configuration file to execute a command on a remote host.
I have the following is my configuration file:

##############################################################config file
MasterServers = CPRG-MRED
ConfigIncludeDir = C:\NetXMS\etc\nxagentd.conf.d
LogFile = {syslog}
FileStore = C:\NetXMS\var
SubAgent = ecs.nsm
SubAgent = filemgr.nsm
SubAgent = ping.nsm
SubAgent = logwatch.nsm
SubAgent = portcheck.nsm
SubAgent = winperf.nsm
SubAgent = wmi.nsm
ActionShellExec=DisplayServices:wmic service get DisplayName,name,startname
##############################################################config file

It works fine , but the problem is when I configure that option in a policy :

<config>
    <agent>
        <!-- there can be added comment -->
        <MasterServers>X.X.X.X</MasterServers>
        <ConfigIncludeDir>C:\NetXMS\etc\nxagentd.conf.d</ConfigIncludeDir>
        <FileStore>C:\NetXMS\var</FileStore>
        <LogFile>{syslog}</LogFile>
        
        ###################################### INI SUBAGENTES
        <SubAgent>ecs.nsm</SubAgent>
        <SubAgent>filemgr.nsm</SubAgent>

        <SubAgent>logwatch.nsm</SubAgent>
        <SubAgent>portcheck.nsm</SubAgent>
        <SubAgent>winperf.nsm</SubAgent>
        <SubAgent>wmi.nsm</SubAgent>
        <SubAgent>ssh.nsm</SubAgent>
        <SubAgent>netsvc.nsm</SubAgent>
        <SubAgent>dbquery.nsm</SubAgent>
        ###################################### FIN SUBAGENTES

        <ActionShellExec>DisplayServices:wmic service get DisplayName,name,startname</ActionShellExec>
                
    </agent>
    
    <filemgr>
        <RootFolder>C:\</RootFolder> # read/write access
        <RootFolder>D:\</RootFolder> # read/write access
    </filemgr>

    <WinPerf>
        <EnableDefaultCounters>yes</EnableDefaultCounters>
    </WinPerf>
</config>

It doesnt works anymore and I get an error: Cannot execute action on node CPRG-MCFE: Communication failure
