When trying to access the DNS service on Microsoft Windows Server 2003 (Build 3790) domain controller/schema master via the MMC DNS snap in or locally via the DNS MMC from Administrative tools I'm getting a red "X" through the icon for the DNS Server. The inability to access DNS management via MMC happens on all domain controllers as well.
We've looked at items such as the DHCP client not being started, incorrect DNS setup ( the machine points at itself and another DC ), the DNS service not running ( it is and all DNS queries via NSLOOKUP work correctly ), dslint returns the correct information and functions as expected.
There is the following entry in the DNS event log:
The DNS server could not initialize the remote procedure call (RPC) service. If it is not running, start the RPC service or reboot the computer. The event data is the error code.
For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.
0000: 0000051b
dnscmd fails with RPC server unavailable yet RPC is started:
C:\Documents and Settings\Administrator.DOMAIN>dnscmd /Info
Info query failed
status = 1722 (0x000006ba)
Command failed: RPC_S_SERVER_UNAVAILABLE 1722 (000006ba)
DCDIAG /TEST:DNS /V /E produces the following errors:
Warning: no DNS RPC connectivity (error or non Microsoft DNS server is running)
[Error details: 1753 (Type: Win32 - Description: There are no more endpoints available from the endpoint mapper.)]
Warning: no DNS RPC connectivity (error or non Microsoft DNS server is running)
[Error details: 1722 (Type: Win32 - Description: The RPC server is unavailable.)]
The DNS server could not initialize the remote procedure call (RPC) service. If it is not running, start the RPC service or reboot the computer. The event data is the error code.
A DNS query for _ldap._tcp.dc._msdcs. returns the correct results.
All domain and ADS related activities are working except that I can't manage my DNS via MMC or dnscmd.
Any thoughts or solutions would be greatly appreciated.
