Hi all,
i have a problem with the DHCP test. The status is permanently "No answer". The other tests are working fine.
The Host Monitor version is: 8.72
Server OS: Windows Server 2003 Standart Ed. with SP 2 on virtual Maschine
The DHCP Server OS is : Windows Server 2008 R2 Enterprise 64 Bit
DNS test is working.
IP v6 is disabled in the registry of the DHCP Server.
Test config. is as follow:
Test by: Host Monitor
Test method: dhcp test
Host: DHCP Server IP
Timeout: 5000 msec
Request IP: current local
Test depends on Ping test. (Master test) the test is OK!
I have run dhcpcheck with the parameters:
dhcpcheck -host:"ip address of server"
result ist: script res: Host is alive: 30 ms
What can i do??
Thx for your Help!

If "-clientIP:" parameter is not specified, dhcpcheck.exe sends the DHCPINFORM packet to the server (instead of DHCPREQUEST packet).
HostMonitor always send DHCPREQUEST request. So it looks like your server does not respond to DHCPREQUEST...
May be HostMonitor system has several network cards connected to different network? Or may be IP address used by HostMonitor system is out of DHCP range?
In such case you may specify IP address for the test (instead of using "current local IP" option) so HostMonitor will request IP address from network and range supported by DHCP server.

Hi Alex,
thank you for your fast reply.
Yes there are two network cards. The network segments are (1) X.X.0.X and (2) X.X.7.X. I have deaktivatet the second network card and the test works. But we need both segments.
I tried the other solutions before i deactivatet the second network card. But the result was the same. No answer.
Best regards
Yasin

Do you mean you have specified IP address for the test? IP address from range supported by DHCP server? And server does not respond? Strange...
In such case I would suggest to setup Shell Script test item using dhcpcheck.exe usility without IP address parameter so it will send DHCPINFORM packet to the server.

DHCP Test
Hi,
sorry for my late reply.
Yes I tried a specific IP for the test. I also tried an address from DHCP range. The result is the same. No answer.
The result of the test with dhcpcheck.exe: "NO answer:Confirmation packet was not received.
When I deactivate the network card with the IP segment x.x.7.x dhcpcheck result ist: Host is alive 46 ms.

Sorry, we don't know why HostMonitor does not receive answer from your server. Have you checked DHCP server logs? Does it receive requests from HostMonitor?
I would suggest to use Shell Script test method and DHCCheck utility without clientIP parameter.
In such case dhcpcheck.exe sends the DHCPINFORM packet to the server (instead of DHCPREQUEST packet) and as you see it works in your case just fine.
