I am migrating from Exch 5.5 to 2003. Outlook 2003 users
work w/Exch 5.5 but when their mailboxes are converted to
Exch 2003, they get messages that the server is unavailble
and slow responese. Prob is that clients' Outlook security
is set to the default of "Kerberos/NTLM Password
Authentication". When change it to "Password
Authentication (NTLM)", it works. Why? We're running A/D
in native mode. What am I missing, where? Thanks!
...login prompt after enabling kerberos authentication
we have enabled keberos authentication in our sharepoint farm.
After enabling kerberos, every time we open the site, it prompts for
username and password. Once entered it works fine.
Is there a way to disable this prompt?
i went thru technotes and have done all configurations mentioned like client
using integrated windows authentication etc.
Thanks and Regards,

...Office 2004 Kerberos?
Does anyone from Microsoft or the beta team know if Office 2004 will
offer Kerberos v5 support? I know there are many college campuses and
businesses that rely on Kerberos for security with the e-mail.
Personally I have to use Entourage for all e-mail except my college
mail because of the lack of Kerberos support. Thanks!
It's too soon to know the future, as it has not happened yet.
It would be a good idea to send your suggestion to Microsoft requesting
Kerberos support for Office 2004. You can let Microsoft know your suggestion

We have a couple of Exchange servers (E2003 on W2003) with several thousands
of mailboxes and a few times we have run into the problem of memory
depletion due to the cached Kerberos tokens. The servers have 4 gigs of
memory and we are using the "/3GB and /USERVA = 3030" -options in boot.ini.
I understand (correct me if I am wrong) that using the "/3GB and /USERVA =
3030" -options reduces the maximum paged pool size to 245 MB and that's
where the cached tokens reside.
I was wondering whether I could use the "PagedPoolSize" registry value (in

Problem i have is that when users are logged in to crm webclient,
using the alias (http://crm) of the server in the address bar, they
will eventually be prompted for their logon credentials. This logon
prompt does not happen when they fire up crm, so it appears that
integrated windows authentication is initially working. However, after
a period of time (random- can be less than an hour, or more than an
hour), they will then be prompted for their credentials.
