I have been following the instructions in: http://technet.microsoft.com/en-us/library/aa997232(EXCHG.65).aspx but when I got to: http://technet.microsoft.com/en-us/library/aa998910(EXCHG.65).aspx It said to check settings in: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeIS\ParametersSystem Regedit does not show: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeIS at all. Just not there. Nor does \Software\Microsoft\Rpc have a RpcProxy setting. Any ideas? Thanks

Hi, Sounds like Exchange server 2003 is not installed on the server. HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeIS should be there (and have been on all the systems I have checked) Leif

I didn't wait long enough for the registry to populate. The settings are there now. Thanks, Leif. Now . . . to try it
