Hi all. I'm having trouble querying DHCP server from Windows PE. Specifically I am trying to query the hostname we have stored in option 12 of the reservation in DHCP. I can query it on XP using netsh dhcp server if I copy the dhcpmon.dll file from Server 2003. I just add helper dhcpmon.dll and I can then run netsh dhcp server commands. I think it also works with Windows 7 / Vista if I use the Server 2008 dhcpmon.dll in the same way. I just can't get it to work from Windows PE. For some reason, I can't add the helper. I'm using both Win 7 and Server 2008 R2 boot.wim and the 2008 R2 dhcpmon.dll in my tests. I suspect some other components are missing to be able to add the helper - would anyone have an idea what they could be? Also I have tried using a script that uses dhcpsapi.dll to do the query. Again, this works fine on XP and Win 7 etc, but not on PE. It complains, first, of DSAUTH.dll not being present... I added this in but it couldn't initialise the dll. I couldn't regsvr32 it either. I feel there may be a common component missing for either solution to work. SO... Does anyone either have any ideas of how to resolve one of the above issues, or another way to query option 12 DHCP from PE? Again, using Server 2008 R2 and Windows 7 boot.wim, so that's likely to be PE 2.1/3.0, but I haven't checked the versions. Away from work right now, but if you need some more info will supply it as soon as. Thanks!
