Re: Single user unable to access OWA

Hi Andy:

In cases of this type, isolated to a single user, I suspect a cached local
password. Look on his workstation in Users and remove any passwords for any
user (assuming there is one) with the same name as his SBS logon user name.

You may get more response in the SBS 2003 Newsgroup.

SBS public Newsgroups:

SBS 4.x: microsoft.public.backoffice.smallbiz
SBS 2000: microsoft.public.backoffice.smallbiz2000
SBS 2003: microsoft.public.windows.server.sbs

if your current news server does not carry the mentioned groups you should
be able to connect directly to news.microsoft.com

I have a single user who cannot logon to OWA via http(s)//fqdn/exchange.
The
user is refused access with a "username or password invalid" style
response.
The SBS server logs a 529 Security failure for username Domain\user, logon
type 3, Caller User Name IUSR_SERVER.

Previously, the user has had no problems accessing OWA, although the
problem
may have started when he was required to change his password (on the LAN)
due
to password aging. Alternatively the problem may be coincident with the
November Windows update round. The user can log on normally onthe LAN
with
the credentials rejected by OWA. The OWA failures occur on all external
clients. He has not tried to connect to OWA via the LAN and is not on site
to
check this.

No other users have OWA access problems. I note that the SBS server logs
a
type 8 logon for IUSR_SERVER when they access OWA, but no other logons
associated with the specific use logging in. This contrasts witht he
failed
user for which there is no IUSR_SERVER logon (just the fialed type 3)

SBS 2003 SP1 with Echange 6.5.7638.1 and all patches other than W2003 SP2.
All IIS default website permissions and Exchange virtual Folder
permissions/access settings are correct (as per MS KBs)

Any help would be much appreciated.
