HTTPS Merge Client Synchronisation Issues

Hi


We have about 70 clients, each with their own databases synching to a copy of their database on a remote webserver. They synchronise using a Windows Service which we wrote using RMO.



For completeness, our setup is as follows:

subscription.CreateSyncAgentByDefault = False -- I wrote a windows service to synchronise
subscription.UseWebSynchronization = True
subscription.InternetSecurityMode = AuthenticationMethod.BasicAuthentication
subscription.SubscriberType = MergeSubscriberType.Anonymous



Sometimes, one of our clients synchronisation goes up the spout - it might take hours to synchronise - despite their internet connection being fine. And once this starts to happen, nothing will fix it. We've restarted their server, rebooted their router etc etc.



Well, the only way of fixing it is to recreate the publication, copy the backup, reinitialise and start again, which costs us a days work and inconveniences the client greatly.


What would be the likely trigger for this. How can we stop this happening again.


If it helps we could create a trace to help resolve this.....



Regards
