OWA continually asking for username and password

[benfolds]

Hello all

I am on a clients site trying to connect to my companies exchange server using OWA. I have been here in the past and all has been fine, however as of today the username and password box pops up and even though I am using the correct username (domain\username) and password it keeps coming back. OWA starts to load but then stops. I have verified that my account is active.

Any ideas? The issue must be with the ISA setup at this site as other users are successfully getting access to OWA from other sites, and I am able to if I use a dial up connection to the web.

Thanks in advance

Open ie on the system having problems.
Pull down the tools menu and go to the security tab.
Click the local intranet icon and then the sites button.
Ensure that the checks are in the boxes that apply (we check all 3).
If the owa server is outside your lat/ldt you can bypass the proxy by adding a site and content rule.
Probably the best place to start is by looking at your ISA logs if all else fails.

Hi there rubbaninja

Thanks for your advice, I've tried those options already though The weird thing is that from several machines on different sites with different ISA servers I have experienced the same thing.

I have come to the conclusion that it is something to do with the way that ISA is configured, just got to figure out what.

thanks

The LAT is probably your biggest thing.
If your not running Auto discover off of DNS or DHCP (

http://wpad/)

but have it configured under the server properties, client config and firewall config you will see issues with LAT.
Im not 100% positive on it but I believe I ran across that info on ISAserver.org

Thanks for that, I'll keep digging. When I resolve the issue I'll post the solution.

I had this problem my self, when using older IE (<= 5.0)versions. I also had this problem with Opera but with their latest version that should be fixed.

I was typing a long reply concerning configuration of &quot;ask user for auth&quot; under outbound connections in the ISA server properties when I thought a bit deeper that your working with inbound and publishing (however you may want to remove the requirement to auth the user on inbound connections and manage your permissions through your rules and access policies) There is an article on this subject on isaserver.org. I found this out the hardway due to applications running through the browser like java applets and online meetings. The application will throw an anonymous request first which causes the app to fail.

However, since your coming in... it's possible that your logs hold the key to your pickle.
If the prompt isn't telling you if it's ISA or Exchange.... Open up command prompt and run netstat -an while attempting to connect.
This will tell you what your connected to. If you don't see your mail server ip address then it is definately your ISA server

I'm just throwing out ideas, may not help but I hope it does!

Here is an interesting situation-I have the same problem, but only when accessing OWA from within the network using the fully qualified name
&quot;

http://server.domain.com/exchange&quot;.

From the Internet, it works fine, if I use just

http://servername

(or DNS alias)/exchange it works. My issue started when I added a DNS entry for the local of mail.domain.com. The same name is used on the Internet for traveling folks to get their e-mail. The DNS works fine via outlook or the web address (Iexplorer) as long as I don't use the full name, so it may be a DNS thing as well.
