Hey Swests,
I have not yet got this resolved. As I only have 3 users at the moment using Iphones, I simply set the phones to only sync on a manual basis. This works for the moment.
I had not come across that Experts-exchange article, so might just give that a go sometime. If you have some success with it, please let me know.
Cheers!

Hi J-Law

Got just 2 messages over night, so not 100% better.
I've been tweaking the min and max vales and assuming that the router times out at 60 seconds I have set Min to 30 secs and Max to 50 secs. IISRESET and now we wait and see (again)...

What are your ISS logs looking like? Mine grow to about 100mb showing each user's active sync connections, over and over again.
Since you made the changes, has the frequency of these inbound sync connections lowered?
Thanks for posting back and keeping this thread updated!

AAARGH - well that didn't work. ActiveSync message still appearing and yes, IIS logs are now massive! And the extra work is draining the iPhone batteries like only an iPhone battery can drain!
I did some more research and also contacted Draytek support - their suggestion is to change the TCP SYN timeout to more than 540 (the default is 60). Microsoft suggest at least 900 secs.. so I've reset the registry back, deleting the Mix and Max timeout values and used portmaptime -s 900 on the router.
The reply from Draytek is as follows
My portmaptime settings are now...
So as you can see I've increased TCP WWW and TCP SYN from the default of 60.
Let's see what the next 24 hours brings...

The reply from Draytek is as follows
The HTTPS time out value is not available on the router. To resolve active sync issues, normally TCP SYNC values is changed. It requires a larger value like 540 secs.
TCP Sync applies to all TCP protocols which in theory should also apply to HTTPS/SSL even with different port number.
My portmaptime settings are now...
Code:
> portmaptime -l
------ Current setting ------
TCP Timeout : 86400 sec.
UDP Timeout : 120 sec.
IGMP Timeout : 10 sec.
TCP WWW Timeout: 900 sec.
TCP SYN Timeout: 900 sec.
So as you can see I've increased TCP WWW and TCP SYN from the default of 60.
