Hi, I would like to set up our Exchange 2003 server (Runs on Windows Server 2003 and AD too) for Mobile access to synchronizing any mobile device. So I have choosen single server set up, but at the first step I have a problem. Adding RPC over HHTP proxy windows component does not make RPC virtual directory! Tried to install with stopped Exchange server, no success. So I can not set up remote accessing with mobile devices. OWA is working fine. Is this a bug? Regards, Yesname

The RPC directory has nothing to do with mobile device synchronisation. If you are following instructions that says it does, then I would strongly doubt anything else is writes. The RPC virtual directory is used by Outlook, with the RPC over HTTPS feature. Therefore your inability to connect mobile devices to Exchange is unrelated. If you want to use Outlook, I suggest that you remove the RPC Proxy function, then run IISRESET to ensure the IIS metabase is updated, then reinstall it. The directories should appear. If they do not, then there is chance you have a more serious problem. Certainly not a bug - it would be well documented if there was a bug in a version of Exchange/Windows that is pushing 8.

IIS Reset did not help. RPC virtual directory has not created. Everything seems fine, except that dir. I watched with processmon, no error. IIS log file does not contains any error. OWA works fine, only problems I can not install RPC over HHTP fully and mobile access does not work. (Every ActiveSync options is set right.)

As I have already said - RPC over HTTPS has NOTHING to do with ActiveSync. If you are trying to get ActiveSync to work you do not need to have the RPC Proxy installation. However the only time I have seen the virtual directories fail to create is when IIS was corrupt. That required a reinstallation of IIS, which means removing Exchange as well. http://support.microsoft.com/default.aspx?kbid=320202 Simon.Simon Butler, Exchange MVP Blog | Exchange Resources
