I am getting a 500 error after logging into the OWA logon screen.  If i try to access OWA via the xxx.com/exchange url, i get an NT authentication box which will allow me to access my mailbox.  I am still in testing mode and have not yet uncovered any additional issues as of yet.

So when you go to domain.com/exchange and log in it works OK?
When you go to domain.com is when the 500 error happens?
I would turn on forms based authentication

Also are you using SSL...

not currently using SSL.  I am building a new environment and have not moved that over as of yet.
Also, Exchange is not installed on the www.domain.com server.  Should I install Exchange on the web server as well?  I am working on turning on forms-based authentication.

No no need to install exchange twice.
What happens when you go to xxx.com/exchange
You should get a log in box put in domain\username and then the password does it work?

Also when you switch on forms based auth make sure to add the domain so your users dont need to the "domain\" anymore

Great.  I didn't think I needed to install Exchange on the www server.  You are correct regarding xxx.com/exchange.  I am not ready to setup SSL, for I do not have a CA signed certificate.  We had a self signed cert only in our current environment.
I do want to setup SSL, but don't think that will happen today.
Back to the issue at hand.  I had to create 2 Virtual Directories on my www server to point to /exchange (this works after basic authentication) and http://exchangeserver/exchweb/bin/auth/owalogon.asp.  This is were I get the OWA logon screen but after putting in my credentials, I get the 500 error.

You should nto have to create any new virtual servers.  If xxx.com/exchange works
then all you need to do is simplfy the URL

this has been done with redirection via redirects.  The /exchange redirect works, but the other virtual directory that I created to access the owa login screen gives me the 500 error.  How can I fix that?

I found another string on this site indicating that I should delete all of the owa virtual directories and then recreate them.  What do you think?

Thats not an issue at all.  When initially setting mine up I messed something up so I had to redo it.
I used this article though, I didnt just delete

correct.  I can get to that logon screen, but when I try to authenticate it fails with the 500 error.

Why are you going there instead of just
http://servername/exchange

In the current SBS environment, that is the logon screen that the users see.  Plus, i feel that the other way I'm trying to do should work.

Yes but there is some redirecting that goes on.  You need to access it the way I showed.
You can shorten the url though but thats it

I am really sorry i just don't get it, if I can get to the OWA logon screen, regardless of how I got there, why shouldn't i be able to get past the 500 error and see my mailbox? When I point them to the /exchange path, they get a basic authentication window and then you click OK then wham, your in your mailbox within OWA.  No OWA logon screen.

http://exchangeserver/exchweb/bin/auth/owalogon.asp  <------ you
http://exchangeserver/exchange  <------ default
2 totally different virtual servers


You have to hit the exchange virtual server you cant go directly to the exchweb virtual server.

i guess i dont understand the only way to log onto OWA is through /exchange way
Now you can simply the URL so your users dont have to type in the /exchange just http://exchangeserver


To simplfy URL

I got it to work finally.  I added the owalogon.dll to the Isapi filter, then added SSL.  All is good now.  Thank you so much for your assistance and patience with me.
Thanks,
Adam
