Exchange Server

Have Exchange 2003 running on SBS2003 (SP1 not installed) and has been
running great for over a
year. Many users use Outlook 2003 remotely using RPC over HTTPS with no
problem. Then one user running Windows Server 2003 STD on a laptop (a client
machine) applied SP1 and now Outlook connection via RPC over HTTPS is
broken.

The Outlook authentication request appears again and again - it is never
satisfied. Tried running it as "outlook /rpcdiag" and don't get any
additional information that is helpful. Just simply does not authenticate.
Had Virtual PC running on the Windows 2003 machine so we tried using Outlook
2003 from within VPC (On XP as the host OS) and everything was fine.

The firewall is off on Windows 2003. Event logs on the client show nothing.
Event logs on the server show nothing either. Even the log file from IIS on
the RPC directory seems to have everything correct - a 200 response from IIS
on RPC_IN_DATA and RPC_OUT_DATA. And I have gone through KB article 833401
more than once to make sure everything is OK. Also fooled with the new
registry settings for RPC security (on client) to no avail.

So it is definitely a problem with using Outlook 2003 with RPC over HTTPS on
a Windows 2003 SP1 client.

Any ideas where to look on this one or should I just scrap SP1 on the
client? Thanks for any help.

Also - additional information - use rpcping on this machine and it gives no
errors when connecting to the rpc proxy. Used this command:

C:\Program Files\Windows Resource Kits\Tools>rpcping -t ncacn_http -s
com01.****.net -o RpcProxy=outlook.****.net -P "rhertzler,****,*" -I
"rhertzler,****,*" -H 1 -u 10 -a connect -F 3 -v 3 -e 6001

So it really seems to be something with Outlook itself running on Windows
2003 SP1. Maybe it has to do with the fact that the exchange server is at
the domain ****.net and the laptop client running Windows 2003 SP1 is at
****.local. Strange thing is that WITHOUT SP1 on the client, everything
works fine.
