I saw it the first time.
How the site resolves on the Internet has absolutely no bearing on how
it resolves internally.
Oranges and roadapples...

Hi Jim, 

 

My last message didn't show up on this thread, wonder why. So here goes
again.

 

These people had there server setup as their domainname.local initially,
and use their owa.domainname.com for OWA, email ,etc. I recall that
there can be issues when using .local as suppose to .com especially when
doing RPC over HTTP. Do you have any ideas on what I should do other
than rebuilding their entire network? :-)

 

Thanks

Andrew

RPC/HTTP is only supported on WinXP and later.

Hi Jim,

 

The client runs Office 2003 Pro, thus Outlook 2003. We are installing
SP1 as I type this message and will test it again, but can I be sure
that its related to not having SP1?

 

We have the client machine connected to a DSL modem in the same office
but non of the traffic goes through the server, it all goes out to over
the internet back into the office. 

 

Thanks

Andrew

RPC/HTTP doesn't use the RPC application filter.

Any "real" RPC traffic you see is a result of client misconfiguration.

 

What is the client you're using (OS/SP/Office ver / patches)?

Where is the client operating from; internal or external to ISA?

Hi,

 

I have setup RPC over HTTP along with OWA using Tom's Exchange / ISA
info. Though I don't think there is any problem with his material I am
having a problem wirh RPC. The OWA with SSL works flawlessly. 

 

When I setup the log in ISA to only look at the machine that we are
using on the external side to connect to RPC over HTTP its able to
negoicate with HTTPS on 443 without any problems but the RPC (all
interfaces) id denied access by the default rule. I am wondering is
there something else I need to set on ISA to enable the RPC protocol to
work?

 

Thanks

Andrew
