Hi all

RPC over http
Hard to say without any configuration info. Most likely you have the option
"on fast networks..." enabled so it will still try to connect via RPC over HTTP on the local network. -- Robert Sparnaaij [MVP-Outlook] Coauthor, Configuring Microsoft Outlook 2003 http://www.howto-outlook.com/ Outlook FAQ, HowTo, Downloads, Add-Ins and more http://www.msoutlook.info/ Real World Questions, Real World Answers ----- "Simon" wrote in message ...

RPC over http
Yes that is what i want it to do, but i don't want it to prompt me for a
username and password as the user will have already logged onto the laptop "Roady [MVP]" wrote: Hard to say without any configuration info.

RPC over http
FWIW, as long as the option is set to use basic authentication then one has
to supply credentials regardless. The sad part is that while you can go with NTLM authentication for the RPC/HTTPS proxy part, there are many firewall solutions (e.g. PIX) that trash the authentication attempt and cause RPC/HTTPS to fail.

RPC over http
Thanks for both your answers.
So what you are both saying is that if the user connects their laptop onto the domain, the same as anyone else, if they have RPC over HTTP enabled it will always ask them for their credientials. (I have windows integrated authentication enabled on RPC of IIS) So how do all the other users authenticate with exchange because they are not asked twice??

RPC over http
Again; is the option "on fast networks..." enabled or disabled?
If enabled and you have Basic Authentication enabled, you will also connect to Exchange via RPC over HTTP on the local network and thus you must supply your credentials. -- Robert Sparnaaij [MVP-Outlook] Coauthor, Configuring Microsoft Outlook 2003 http://www.howto-outlook.com/ Outlook FAQ, HowTo, Downloads, Add-Ins and more http://www.msoutlook.info/ Real World Questions, Real World Answers ----- "Simon" wrote in message ...
