Hello all,
I am facing a problem in using dcdiag.exe.
I am using dcdiag.exe to diagnose the installation/configuration of a
hardened Windows 2000 box.
I have configured DNS server and there is no problem in the name resolution.
When I used dcdiag.exe on a hardened box without ADS installed, I got the
following result:
E:\Program Files\Support Tools>dcdiag /test:DcPormo /DnsDomain:admin
/newforest
Starting test: DcPromo
Messages logged below this line indicate whether this domain
controller will be able to dynamically register DNS records required for the
location of this DC by other devices on the network. If any
misconfiguration is detected, it might prevent dynamic DNS registration of
some records, but does not prevent successful completion of the Active
Directory Installation Wizard.However, we recommend fixing the reported
problems now,unless you plan to manually update the DNS database.
This domain controller cannot register domain controller Locator DNS
records. This is because it cannot locate a DNS server authoritative for the
zone admin. This is due to one of the following:
1. One or more DNS servers involved in the name resolution of the
admin name are not responding or contain incorrect delegation of the DNS
zones; or
2. The DNS server that this computer is configured with contains
incorrect root hints.
The list of such DNS servers might include the DNS servers with which
this computer is configured for name resolution and the DNS servers
responsible for the following zones: admin
Verify the correctness of the specified domain name and contact your
network/DNS administrator to fix the problem.
You can also manually add the records specified in the
%systemroot%\system32\config\netlogon.dns file.
......................... inmum0048 failed test DcPromo
I tried it on a unhardened box and it yield the same result!!
What could be the problem?
After this I configured ADS on a unhardened box and tested with dcdiag,
following are the results:
E:\Program Files\Support Tools>dcdiag /s:inmum0050
Domain Controller Diagnosis
Performing initial setup: Done gathering initial info.
Doing initial required tests
Testing server: Default-First-Site-Name\INMUM0050
Starting test: Connectivity
INMUM0050's server GUID DNS name could not be resolved to an
IP address. Check the DNS server, DHCP, server name, etc
Although the Guid DNS name
(27c53983-c5be-4863-996b-c20af4099f36._msdcs.admin) couldn't be
resolved, the server name (inmum0050.admin) resolved to the IP
address
(10.9.65.200) and was pingable. Check that the IP address is
registered correctly with the DNS server.
......................... INMUM0050 failed test Connectivity
Doing primary tests
Testing server: Default-First-Site-Name\INMUM0050
Skipping all tests, because server INMUM0050 is
not responding to directory service requests
Running enterprise tests on : admin
Starting test: Intersite
......................... admin passed test Intersite
Starting test: FsmoCheck
......................... admin passed test FsmoCheck
I have configured DNS and nslookup works fine.
Why is this happening?
What is the reason for the failure to resolve the Guid DNS name?
Why does it fail connectivity tests?
What is the reason for the directory services not responding to the
requests?
