I need to fetch the current leases from a Windows dhcp server by a script. Or is a kind of dhcp query possible?

You can use netsh dhcp server

netsh dhcp server dump

netsh dhcp server show all

then parse the output to the way you want.

What ipajones suggested will work, but if you have more than one scope you can run this as a .bat and get them all at once:

For /F "skip=5 delims= " %%a IN ('netsh dhcp server \\dhcpservername show scope') DO (
      if not %%a == Total (if not %%a == Command netsh dhcp server \\dhcpservername scope %%a show clients >> leases.txt)

Thanks for the answers. I tried "netsh server \\<server> scope x.y.z.c show clients", but this cmd doesn't include the client's name. I need the couple client's name + ip-no.
I modified the script dhcpcheckerv2.2 tow actual situation; it runs, but doesn't mail a result. Not sure what's wrong.

The scripts works, but doesn't deliver the client's name + ip-no. Any other idea?
