Ping Fails – Destination Host Unreachable

[notnAP]

I have an odd bug. I cannot ping from BatchPatch to one particular host.
Pings return only DestinationHostUnreachable
But here’s the oddity – I can perform every other BatchPatch function that I use, including

– Download and install updates
– Get Host Name
– Get Last Boot Time
– Get MAC Address
– Get CPU Info
– Get Pending Reboot status
– Send Message
– Create/Modify/Execute remote Commands
– wmic bios get serialnumber successfully returns the host box serial number
– powershell “Get-PhysicalDisk | Select-Object FriendlyName,MediaType | ft -hidetableheaders” successfully returns the disk information
– Get RAM Usage

I can ping successfully from the windows cmd line on the pc where I am running BatchPatch.
I have also
– flushed dns on the batchpatch system.
– disabled Windows Firewall (Domain + Public + Private) on the system I am trying to ping.
– Checked the firewall rules for printer and file sharing IP4 ping and WMI IP4 on the remote system
– Checked the dns server for any odd or out of date entries for the remote system. dns lookups performed to determine the remote system ip are all successful and returning good data.
– rebooted both systems multiple times since the problem first appeared.

Both the remote system (“Timson2-ACX” and my batchpatch system “Panton-off”) are on the same local subnet (10.0.0.1/21). They are connected via switches without any VLAN trickery. No network firewall exists between the two systems.

I’m out of ideas.

Very peculiar. I would try adding the IP address directly as a row in BP. Also try adding the FQDN (e.g. “Timson2-ACX.yourdomain.com” instead of just “Timson2-ACX”). See if either of those works.
