Guest Haggis Posted July 15, 2007 Posted July 15, 2007 i have a weird problem. (win2K3 servers) I am moving dhcp fom server A to server B. i have successfully exported and imported DHCP data fom one to the other. I have authorised Server B and tried to unauthorise Server A. When i do this i get a 'Parameter in incorrect' error. A the moment i have both Serve A and Serve B as Authorised DHCP servers. One thing i notice though, when i go to the menu to 'add server' in the DHCP console from the list of DHCP servers, I see the name of the new server and the name of the old-old dhcp server prior to the current one, they have the same IP address. Maybe something weird hapened when i transferred DHCP from the older server to Server A some time ago. it seems that in AD that there is match up of older server name to current ip address. My question is, how do i get the Server A removed as an Authorised DHCP server when there seems to be some name confilct. Can i do this manually through adsiEdit or something. Alsois there any issue having 2 Authorised DHCP server on the same LAN. Thanks in advance
Guest Haggis Posted July 16, 2007 Posted July 16, 2007 RE: Unauthorize DHCP I managed to sort it out i used the netsh command to manually remove (unauthorize) the old server. Now clients are contacting the new DHCP server. "Haggis" wrote: > i have a weird problem.

Guest johnny_mango Posted August 9, 2007 Posted August 9, 2007 RE: Unauthorize DHCP I had the same problem which appeared to be caused by a change to the server´s FQDN since being authorized.
