Hi!
First of all I have a criticism to ISA 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
