My first attempt was not posted so I have re-posted:
I am currently running an NT4 domain with exchange 5.5 (BDC) and I have recently had to install outlook web access for internal use.
The exchange server has service pack 4 installed, and the OWA server which is on a separate box is on a BDC and has IIS 4 and the OWA add-on installed
The test clients are either windows 2000 professional or NT4 workstation ( all have up to date service packs and patches )
(All servers have Service pack 6)
I have followed what think are all the required steps but when I attempt to log onto the server I am prompted for a user name and password 3 times, then the screen goes blank. Searched MS knowledge base but the only relevant post I can find suggested virus scanning software to be the cause of the problem , and their is no virus scanning on either the OWA server or any of test clients PC’s.
I have insured all of the following has been done:
Logging on with Domain\username
Granted the 'Everyone' group log on locally rights, on the OWA server
Insured WWW services on the IIS, allows only Anonymous access and Basic Authentication is checked
Added the domain name to Basic Authentication access properties
Note: When I try logging onto the OWA server itself I still get the same problem, event log displays the following
Event ID 100
The server was unable to logon the Windows NT account 'Domain\Username'
due to the following error: Logon failure: unknown user name or bad password.
The data is the error code.
0000: 2e 05 00 00
I have synced the server with the PDC just to be sure all account info is correct then logged using several different domain accounts this all seem fine. It seems that IIS is not authenticating with the NT SAM or something not sure? so your help on this matter would be very much appreciated
Thanks in advance
