DHCP scope option reporting

Dear Experts,

Is there any code available, which would allow me to pull the value of a specific DHCP scope option, rather than listing them all, as "netsh dhcp server scope <IP> show optionvalue" does?

Thank you,

Sergey

Not with the the NETSH command afaik.

You can soon run that through a FIND or FINDSTR command, e.g.

netsh dhcp server scope <IP> show optionvalue | find "optionvalue 3 "

Should bring back the default gateway line (from memory.. I thibk that was 3!)

You could use a FOR command then if necesssary to split of the value from this line:

@echo off
for /f "tokens=3,5,8,10* delims= " %%a in ('type irn70136.txt ^| find "optionvalue 3 "') do (
   echo Server = %%a
   echo Scope = %%b
   echo Option %%c = %%d
)

Please let me know what you have as a script now and what output you are/aren't getting and will see what can be done.  Give me the output of

netsh dhcp server scope x.x.x.x show optionvalue

with any details amended if you wish and what you want out of it - could be you get subtly different output to the script above which is part of one for pullng the details out of a Server 2003 network.

Hello dragon-it,

I was not able to get separate output for each individual DHCP cope option. However, using the following type of code allows for manageable output parsing:

        Set objWshScriptExec = objShell.Exec(strQuery)
        Set objStdOut = objWshScriptExec.StdOut

        Do Until objStdOut.AtEndOfStream

              strLine = objStdOut.ReadLine
             
        Loop

Thank you for your help.

Best Regards,

Sergey

Did not completely resolve my issue, but was quite helpful at pointing me in the right direction.

Fair enough.  Would gladly of assisted more if given the chance (and an example of the failing output). Batch text parsing can be a little tricky but should work as long as the input formats are known.
