Re: unmanageable DNS

I have the same EventID: 140
everything is working perfectly 100% except i can't open the DNS from the
MMC due to RPC problems
tools i have used in troubleshooting:
- Replmon
- Netdiag
- DCDiag
- DNSLint
- DNSCMD
- rpcping
- Regedit
evrything is awesome except this :( i did exhaust all the ways but with no
luck any IDEAS?

Hi

My serves are standing in DMZ zone so I've got blocked many ports.
I've configured AD as Microsoft said and Directory Services works ok.
When I delete registry key
HKEY_LOCAL_MACHINE\Software\Microsoft\Rpc\Internet\ports the mmc snap
working ok (localy and remote) but when I got this reg key I can't
connect to DNS via MMC (localy and remote).

How shoudl I configure DNS to work with static rpc.

Thanks,

Honestly, I've never tried it with DNS, but I can tell you this much: MS
DNS will communicate with other Windows machines (whether thru DNS queries
or simply trying to conenct to the machine using an MMC console), with
dynamic ports. Connecting to a console is not really a DNS port, but
rather the RPC ports. I have not configured such as thing as for RPC
traffic, because those articles depict specific domain RPC traffic. What
you're looking for is standar network communication & authentication
between domain members which includes numerous ports. If you look at those
articles, they show what ports and their ranges are required. Maybe you
can create specific rules between specific machiens allowing those ports,
or create a VPN between the DMZ machine and the internal network, which
I've seen many admins have successfully configured in your type of
scenario.
