UPDATE 10/4 6:47 EDT
I have been going through all the comments. THANKS!!! I did not know about the techniques listed, so they are extremely helpful. Sorry for the slow update. As I mentioned below, I got behind with this yesterday so work cut into my evening.
I ran a port scan. The first syntax, -p, brought no joy. The nmap software itself suggested changing to -Pn. That brought an interesting response:
nmap -Pn 1-9999 <Local IP Addr>
Starting Nmap 7.93 ( https://nmap.org ) at 2024-10-04 11:44 BST Failed to resolve “1-9999”. Nmap scan report for <Local IP Address> Host is up (0.070s latency). All 1000 scanned ports on 192.168.0.46 are in ignored states. Not shown: 990 filtered tcp ports (no-response), 10 filtered tcp ports (host-unreach)
Nmap done: 1 IP address (1 host up) scanned in 6.03 seconds
Just to be absolutely sure, I turned off my work computer (the only windows box on my network) and reran the same syntax with the same results.
As I read this, there is definitely something on my network running windows that is not showing up on the DHCP.
In case it helps your troubleshooting, ICMP (ping) is typically disabled by default on Windows.
Thanks. It is not responding to ping.
Your command needs to look something like this:
nmap -Pn -sVC -p- (IP) -o scan
-Pn skips the availability check per ping
-sVC performs a version and a script scan so you get more information
-p- scans ALL ports
-o puts out a file called scan.nmap
If you want you can share that output afterwards for further info.
Edit: You can also try enumerating the directories on the server if you find no content. I can help you with that if you want.
