Try checking your IIS admin for URLScan.. Check the web site properties, isapi filters, check the default and exchange web sites Also try checking the iss log on the exchange server ( not front end ) Can you connect to the mailbox directly on the exchange server? Check your authentication methods

There have been no changes to either of these machines and this issue "appeared" out of nowhere. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Fyodorov, Andrey FTL Sent: Wednesday, March 10, 2004 9:27 AM To: Exchange Discussions Subject: RE: OWA Authentication issue You got some interference there, probably your firewall. I have seen this happen. Try using OWA with SSL (you will have to get a digital certificate for setting up SSL on the front-end server). Usually when firewall causes these problems with OWA, using https takes care of it. I guess because the traffic is encrypted, the firewall can't screw it up. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bennett, Josh Sent: Wednesday, March 10, 2004 9:20 AM To: Exchange Discussions Subject: OWA Authentication issue Hello all, I am having an issue that has apparently come out of "thin air". W2K Advanced Server SP4 on all servers, E2K EE SP3 w/ all current hot-fixes. I have a FE/BE setup for OWA (which is installed on a stand-alone server). For reasons un-be known to me, the OWA server has begun to prompt for login credentials multiple times. If you enter the correct credentials the first time, then click cancel on the next login box it stops asking you to authenticate and allows you access to your mailbox/PF's. If you keep entering your credentials it just continues to prompt you over and over. There are no errors on the OWA server, the IIS logs appear to be normal, I have double (and triple) checked all the appropriate permissions for Authenticated Users on the OWA box. I have triple checked the Directory Permissions in ESM and in ISM. I am at whit's end here and have no idea where else to look. I have looked everywhere and found nothing. The most disturbing thing is that all has worked flawlessly for over a year now and this all started about 2 days ago.
