I have Exchange 2000 installed on Domain controller. When Administrators access their mailbox there is no problem, but when domain users try to access mailbox it asks for user name/password again and again.

Directory security for Exchange in IIS is set to Basic Authentication. The virtual directories for Exchange in IIS are marked RED.

What should I do to solve this prob?
Any help is appreciated.

Hi Samy!

Users need the right to "Access this server from the network" and "Log on locally". These rights are configured in the security policy for the OWA server. Define these right e.g. for Domain users and then everything should work fine. The default value is to allow only administrators, that's why you have to define these settings manually.

The reason why the virtual directories are marked red is because IIS started prior to Exchange (the last time the server was rebooted). The path to the exchange virtual directories contains the M:\ drive mapping, which isn't created until exchange has started. To fix this go to the IIS admin snap-in, right-click the appropriate server (i.e. the server containing the virtual directories - in case you configured multiple servers in IIS), choose stop, repeat and choose start. Press F5 to refresh the display and everything should look nice. NB! even though the virtual directories are marked red they are still functioning as they should! It's just a "cosmetic" bug (or feature).

Regards,

Johan

Hi,

I have same problem, but have granted "logon locally" and "access this PC from the Network" rights to domain users etc, but I still get a message "Failed to connect to Microsoft Exchange Server <server name>".

If I insert a user as a member of the Administrator group, no problem using OWA. Obviously this isn't possible though.

Regards

Ben

Can you confirm if you started having these
problems after rolling out Service Pack 2 for
Exchange 2000.

My problem is similar to what's described, but I'm not able to resolve my problem with the recommended solutions. I'm running Exchange 2000 with SP3. All Administrators and Domain Users can access OWA from IE. Only Administrators can access OWA from any other browser. What am I missing? I have change security policies to allow local logon and allow access from the network, but no luck. Why aren't security and permissions keeping IE users out like they are keeping users out of browsers like Netscape. I want any compliant browser to function with OWA. Any suggestions?

Hi Shannon!

Check which authentication methods that you have enabled for the Exchange virtual folders. If you have enabled only windows authentication then that's your problem. Netscape doesn't support windows authentication, only basic authentication. But if you enable basic authentication make sure you use a SSL certificate to encrypt the data transfer to OWA, as otherwise passwords are transmitted over the Internet in clear text.

Always change the default settings for the virtual directories in Exchange System Manager, not just in IIS. Restart the Exchange Information Store to propagate the new settings to IIS (ESM settings have precedence over IIS ditto). You must use the IIS settings though to require SSL for the Exchange virtual directories.

Regards,

Johan

Hello Samy,

I had a problem similar to that and here's what I found. When I installed exchange, it only gave me 1 licence for the administrator and of course I could not connect with another use. So, I configured the other licences I bought and my problem was solved.
Hope this can help
