Re: Exchange stops working, VPN / RPC over HTTPS issue?

There should be something in the event log? Your second questions
about rpc\http connection bringing down exchange if vpn made at the
same time; it's highly unlikely unless something is buggy.

I posted on the SBS group about a random occurance where Exchange becomes so
slow it almost stops.  The Outlook clients are trying to retrieve data from
the Exchange server.  If I log onto the SBS console and launch OWA using
localhost, it will time out.  There are no errors generated and a hard
restart is usually required because I cannot stop the mailstore service.

The rest of the network works fine.  There is responsive access to shares on
other servers across the network and the Internet is fast and responsive.
It is only Exchange that bogs dow and it happens about every two weeks.  The
BPA was run and I disabled checksum ofloading, otherwise it was healthy.

What is different about this network compared to countless other network I
have installed is VPN and RPC over HTTPS.  We have sales people with
notebooks in three remote locations and they all use RPC over HTTPS.

We also have a server on the same network running ACT 10 CRM software.  The
remote users synchronize their remote ACT database with the main ACT
database on the server by making a PPTP VPN connection to the server first
(SBS 2003) and then running the sync utility in ACT.

Is there a possibility that an existing RPC over HTTPS connection could
bring down the Exchange server if a VPN connection is made at the same time?
