We have a SBS Server 2003 set up hosting MS Exchange. We have been dealing with end of life issues for this server on many fronts.
On vexing problem as been the sudden surge of smart phone use within our company. It would seem that at certain times, several services peg our poor server CPU. The most notable app is w3wp.exe. We have the appPool settings configured to minimize the impact on the server.(see attached Snapshot)
When we analyze the httperr log, we find that out of a handful of devices, one Android phone in particular is responsible for 3/4 of the entries. Most of the "reason" entry are AppShutdown which may log at a rate of of 4 or 5 times per second.
I tried to get the user to delete his exchange account from the phone so we could reset it, but this user is extremely worried about losing his contacts, even though i assured him that everything was on the server.
So my question is twofold. Is there a simple answer to fixing this? and is there any way I can block a single device from connecting on SBS 2003?
He has an iPad he uses also that is connected through exchange and he can get his mail and contacts that way.
I also attached an aggregated analysis of on httperr log. I imported into MS access ran a query on it (see attached log aggregate).
Any help on this would be greatly appreciated.
