Outlook authentication dialog problem

We recently moved from NT4 and Exhange 5.5 to Windows 2000 and Exchange 2000 on the servers. Our clients are still Windows 98 and will be for a least 3 more months. We're having the following problem with Outlook 2000.

The user logs in and authenticates with the AD server, and opens outlook, either immediately or within a few seconds after connecting (they see mail) they're presented with a dialog box to authenticate with their username, password and domain. The fields are all blank. If they hit cancel 2 or 3 times the box goes away for some time and they're able to fully use their email. Eventually, the box returns.

I've tried looking through all the settings and they are all pointed to the new server. Is there a hidden setting somewhere that could be still looking at an old server?

From within Outlook, click on Tools, Services, Highlight Microsoft Exchange Server and click on Properties. Click on the General Tab, make sure automatically detect connection state is selected. Click on the Advanced tab. Make sure the "Logon Network Security" box says "NT Password Authentication" and neither of the Encrypt boxes is checked.

HTH,

I checked this and the settings are all correct. The dialog box still appears. Thank you for the attempt though.

I asked a friend of mine. He's a nationally recognized expert in MS Exchange and has published several books about Exchange.

This was his response:

I?d love to help, need some more info though.

1. Was it in in-place upgrade?
2. If 1 = no,what was used to migrate accounts?
3. Is there a public folder server that is separate?

With the above issue aside, I would see if they are using OST?s. If so, I would test by deleting the old ost, then recreating, then synching.

Thanks for the help. I'll check the OST thing later but since the problem is sort of resolved since we don't need to have the old servers on, I'm giving you the points.

We didn't do an in-place upgrade. We made a completely new exchange site on a completely new server (with a completely new domain and user accounts with a new naming convention.)

We used outlook itself to migrate accounts, login to the old domain, export all mail locally, switch to new domain settings, reimport mail.

The public folders are on the same server.

I will check on the OST's and get back to you. I actually noticed that the dialog went away for a while and came back yesterday... it coincided with us turning on our old domain servers. I shut them all down again and the box isn't appearing.
