ASP.NET, SQL Server, WPF, C#, VB.NET

I have been trying to reliably synchronize a number of PocketPC devices &  
  
one Smartphone using Exchange ActiveSync on Exch2003SP1.  
  
I have managed to get it working on all three devices successfully, but  
  
then, without warning I get a message about a "Critical error has occurred",  
  
followed by any of "This is not an Exchange server"; "You don't have  
  
permissions" or "A connectivity error has occurred".  
  
It doesn't seem to matter whether I am synching via GPRS or Wi-Fi.  The fact  
  
that I have been able to synchronise successfully (and that if I completely  
  
reset the mobile device it works again) suggests that my settings are  
  
correct, but I am at a loss to work out why it keeps stopping working.  
  
Does anyone have any ideas?

I had the same problem.  Buried in the Active Sync directory on the PDA is a  
  
file that if you erase it, it causes the PDA to completely resync from  
  
Exchange.  Obviously do this over WiFi is you have lots of data in contacts  
  
etc.  It's something like SyncKey (it's a while since I tried this so sorry  
  
for being a bit vague, and I don't have my PDA in front of me right now).  
  
Hope this helps.  br/
