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??

Thanks

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.

But a logon to the laptop is not the same as an authentication against
Exchange.

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

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.

Hi all

Easy one for you all

username/password dialog box and i want to irradicate this as they
have
already authenticated on the network. Can anyone advise me

Thanks
