I have 2 DHCP servers running at a head office. Both are serving the same Regional Superscope which contains a scope for both the head office [172.16.x.x] and a regional branch office [172.17.x.x].
The branch office is having issues with new nodes being added to their LAN being unable to register new DHCP leases with the DHCP servers across a WAN connection to the head office.
There is nothing in the logs which suggests any errors with the DHCP server. I'm really in the dark with this so would like somewhere to start looking! If any further information is needed just let me know and I can post it -- really need a starting point before I go delving any further.
One other thing I will say -- it seems that this was working until recent Server OS patches were applied (prior to my being enganged to look at problems at this site I might add).
Thanks in advance.
