Mustafa,
I noticed a couple of things. You don't need MX records in your internal DNS
database. You do need to publish MX records for external DNS however, if you
want this domain to receive mail from the outside. Also, your first rpcping
example shows exchbe.intra.exchtest.net, yet you don't have
exchfe.intra.exchtest.net listed for your internal DNS, so double check that
if it wasn't typo on your part.
I suggest reading the following Microsoft KB article, if you haven't
already. It has a section that discusses this error response.

Hi!
First of all I have a criticism to MS EXCHANGE newsgroup experts:
Why do you cancel the problem, although the problem still exists? You give
no feedback more, if the problem complicated!!!
I hope you give a tip for the following situation:
I user RPCPING tool to diagnose the problem. I used it in internal
network. If I use as Exchange Server my back-end Exchange named
exchbe.intra.exchtest.net, then RPCPING for all -e 6001, 6002 and 6004
successful. Here is it:
__________________________________________________________
rpcping -t ncacn_http -s exchbe.intra.exchtest.net -o
RpcProxy=owa.intra.exchtest.net -P "administrator,EXCHTEST,*" -I
"administrator,exchtest,*" -H 1 -u 10 -a connect -F 3 -v 3 -e 6001
RPCPing v2.12. Copyright (C) Microsoft Corporation, 2002
OS Version is: 5.2
Completed 1 calls in 218 ms
4 T/S or 218.000 ms/T
____________________________________________________________
But if I use mail.intra.exchtest.net as Exchange Server in this utility, I
have the following error for all 6001,6002 and 6004:
rpcping -t ncacn_http -s mail.intra.exchtest.net -o
RpcProxy=owa.intra.exchtest.net -P "administrator,EXCHTEST,*1" -I
"administrator,exchtest,*" -H 1 -u 10 -a connect -F 3 -v 3 -e 6001
RPCPing v2.12. Copyright (C) Microsoft Corporation, 2002
OS Version is: 5.1, Service Pack 2
Exception 1722 (0x000006BA)
____________________________________________________________
You know, I don't want to publish my back-end Exchange Server in Internet.
That is also not recomended RPC over HTTP in an FE/BE einvironment.
I think the problem is DNS name resolution. Or not? I list my DNS
configuration below and want to also a solution tip:
In external DNS:
mail.intra.exchtest.net 213.183.4.125
owa.intra.exchtest.net 213.183.4.125
On ISA Server:
External address of ISA: 213.183.4.125
Internal address of ISA: 213.183.4.118
HOSTS file include on ISA:
mail.intra.exchtest.net 213.183.4.116
owa.intra.exchtest.net 213.183.4.116
NAT mapping on Netscreen Firewall 2:
NAT address for front-end exchange: 213.183.4.116
In internal DNS:
A record: exchfe.intra.exchtest.net 10.10.4.1 (Front-End)
A record: exchfe.intra.exchtest.net 10.10.4.2 (Back-End)
A record: w3kdc.intra.exchtest.net 10.10.4.3 (Global Catalog)
A record for owa.intra.exchtest.net 10.10.4.1
A record: mail.intra.exchtest.net 10.10.4.2
first MX record: mail.intra.exchtest.net points to 10.10.4.1
second MX record: mail.intra.exchtest.net points to 10.10.4.2
Best Regards
Mustafa
