I can't access the remote web workplace or Outlook web access on windows server 2003

I can't access any of these, either from inside the network or from the internet. I'm quite a newby when it comes to ISA so any help will be appreciated

well to run remote desktop connection on a windows 2003 server you need to put a check mark in the box under remote tab. to do that you need to right click on my computer and go to properties. Click the remote tab and place check mark in enable remote desktop on this computer. then from another pc on the network or even on that server open up your remote desktop connections box and type the ip of the 2003 server. And asw far as your owa problem. are you running exchange on this 2003 server? im not sure what your trying to do. After you get the remote desktop working local. then we can proceed to opening up isa for it to work from outside the network.

here are my notes from when i use to work with isa2000. they might be a little vauge since i wrote them for myself and not to teach other people but im sure you will get the general idea.

To setup exchange server email access thru isa
1.      Open publishing and right click on server publishing rules and select “secure mail server”, next, and place check marks in incoming smtp under default authentication and outgoing smtp under default authentication. Click next, type in external ip address that your email will be setup with in dns with isp provider “ example mail.yourdomain.com translates to public ip address” click next and type ip address of computer running ms exchange, then next and finish. Also add external ip address to incoming web request in isa properties. Click add then choose ip.

To setup owa thru isa 2000 for each domain name
1.      create destination sets. Right click on folders, select new, set
2.      type name of site “example yourdomain”
3.      then select add, and under destination tab type domain name “example mail.yourdomain.com . under path name enter /exchange* and click ok. Then click add button again and type same destination but put path to /exchweb* and click ok. Then click add button again and type same destination but put path to /public*
4.      Then go to web publishing rules and create a new rule
5.      Name rule “example mail.yourdomain.com, then next
6.      Select apply this rule to specified destination set
7.      Select name of destination set created for domain from drop down menu. Select next. Example mail.yourdomain.com
8.      Select apply the rule to any request(default) click next
9.      Then choose redirect the request to this internal web server and type in the ip of the ms exchange server. Click next then finish.
10.      Finished. Now stop and restart services.

To setup terminal server or remote desktop connection thru isa2000
     1.Create a new protocol definition name tsac. Select port #3389,        tcp, inbound. (make sure after you create it to check mark it in your access policy if it is    not set to allow all ip traffic)
     2.Create a destination set for tsac. Select destination ip to external ip address to monitor. “example 63.128.100.59”
     3. Create a server publishing rule called tsac. Select action, ip address of internal server should be ip of computer running terminal server. “example 192.168.1.100”. external ip address should point to ip address monitor the web connection “example 63.128.100.59”. applies to any request.
     4. create a web publishing rule called tsac. Select this rule applies to selected destination set. Choose tsac from drop down menu. Under action choose redirect the request to this internal web server “example 192.168.1.100” applies to any request.
     5. right click on your computer icon at top of isa tree and select properties. Click on tab called incoming web request. Choose configure listeners individually per ip address. Click add. Select server from drop down menu and then choose external ip for tsac to connect to “example 63.128.100.59”. call the display name tsac.

Other important isa notes

1.      add all external ipaddress you are going to use for external applications to the external NIC of isa and reboot. This should be done before any rules are written in isa.
2.      Backup isa array after each successful rule written.

I've followed these notes that you put in. but still no joy. I could however have cofigured something wrong, there are certain point in those notes that I don't completely understand eg.

The /exchange*, /exchweb* and /public* paths you refer to, where would these be located?

and the external ip address to monitor, which ip would that be, the ISA server's or the router's ip?

Thakns for the help so far, I've gotten remote desktop to work on the LAN.

I will have to check my notes. Actullay i can log into one of our other sites that is still running isa2000 and send you some screen shots of what its suppose to look like. It would be the isa servers external nic that it would need to monitor.
this article should help you alot till i get the specific information to you.

UNDER WEB PUBLISHING RULES YOU SHOULD HAVE A RULE CALLED SOMETHING LIKE MAIL.YOURDOMAIN.COM AND ON THE DESTIONATIONS TAB YOU SHOULD HAVE A BOX AT THE BOTTOM THAT HAS THEM THREE PATHS IN THERE. A little hard to explain. you might have better luck with that link.

can you get owa working internal by typing    "ipaddress/exchange" in internet explorer.  internal ip address of exchange server

The screen shots, will be great thanks. I'll take a look at that tutorial. However, I can't access OWA from the internal ip address either. I keep getting the "Error 500, internal server error" error message.
