Outlook over HTTPS client disconnects from server intermittently
Posted on 2008-11-12
I have a client with an SBS2003 (Standard) server running Exchange
(SP2). Their network works well, expecpt for the following issue:
The company owner (who lives in FL) has connected to the office in MD
for approx 2 years now, successfully using Outlook over the Web (RPC
over HTTPS) with no problem. Over the past 6 weeks, however, his
connection using Outlook from his house keeps disconnecting; some days
it works fine, other days it's terrible. When it's bad, it's REALLY bad.
Here's what I've done so far: I have checked their internet connection
speed (Verizon DSL), and the download is not too bad (~950kbps); but
their upload is rather poor (no better than 450kbps). Now, more
recently, we've had other users make RDP connections into the office
to work from home (about 4 users in total, though there are usually no
more than 2 connected at a time).
The timeframe when he started having trouble does somewhat coincide
with the increase in potential RDP connections, but I cannot say for
sure that this is the issue.
I've tried to use a rather "squirrelly" Windows2003 Resource Kit
utility called "RPCPing" to test the RPC connection to the server &
the mail store, but the utility is (currently) failing, though I'm
also unable to connect to the owner Exchange mailbox (via RPC) right
now, either (I have his account config replicated on my PC for testing
Does anybody know if a slow internet connection (specifically the
UPLOAD speed being below 500kbps) will make the RPC and/or Exchange
server kill the connection to the remote Outlook client?
Any help would be greatly appreciated!
