I have two pesky host computers. On both I can logon to a AD UC user account assigned to it. I have set up DNS and DHCP just like normal: in DNS computer1.mysite.com with 192.168.1.5 and computer1.mysite.com with 192.168.1.6 forward and reverse lookup. Both within the DHCP scope of 192.168.1.1 to 192.168.1.100 and both 192.168.1.5 and 192.168.1.6 Reservations were made.
One odd thing in DHCP>win-12345>Scope[192.168.1.0]>Address Leases
Lease Expiration = Reservation (inactive) "should be a date and time"
Type = None "should be "DHCP""
From Server Manager>All Servers>Servers
computer1 error code: "Online - Cannot manage a client-based operating system"
computer2 error code:"Target computer not accessible"
Any help would be appreciated.
