hey guys installed a new vm for testiing, server 2008 r2

ran dcpromo and installed it as a DC, i then configured DHCP and authorized it

Problem is the ipv4 top level icon has a red error icon in it, and wont fish out IPs

the log keeps repeating with erros saying the following


"The DHCP service failed to see a directory server for authorization"

I tried a few things, like checking the credentials in the dhcp settings, removing and reinstalling the role etc.

If its too hard ill just make a new VM and trash this one!, hopin to fix it easy but as ive already configured a bit of of!

Any Event Id? Please....

Did you restart the DHCP Service? If that fails, is the DC otherwise healthy? You can start checking by running NETDIAG and DCDIAG from the support tools.

1) Did you tried to deathorize and reauthorize?
2) Please check DNS configuration if DC is available in ping dc.somewhat.local and responds
3) any 3rdparty/MS firewall active on interface? Are the rules to exclude DNS traffic and DHCP traffic included?

Do you have an other instance of DHCP running on your network (router, firewall, ...)

If you have another DHCP service running then you will not be able to start the SBS DHCP service.

Just checking. Are you authorizing the DHCP server with a user as a member of the Enterprise Admins security group?

drkansari,

Yes ive tried restarting. Above post is the DCDIAG, Few errors in it, NETDIAG does not run, u nrecognized command.

If i ping servername.domainname.local it gets a reply OK

There are no third party firewalls, Its an isolated VM running on vmware workstation 8
The MS firewall is active however.

You need to run this test as an administrator.
Right-click command prompt and select "Run as Administrator"
