Very Strange Errors in WFBS6

SBS2003 Advanced Server

5 Windows XP / Windows 7 clients


All seems to work fine but after a few days the server stops communicating with our phone clients (ActiveSync) and even has Outlook issues.  When I look in the SBS Application log I see 3007 errors stating


Event Type: Warning
Event Source: Server ActiveSync
Event Category: None
Event ID: 3007
Date:  3/8/2010
Time:  8:42:48 AM
User:  BPFFI\brentb
Exchange mailbox Server response timeout: Server: [] User: []. Exchange ActiveSync Server failed to communicate with the Exchange mailbox server in a timely manner. Verify that the Exchange mailbox Server is working correctly and is not overloaded.


If I reboot the server it starts working again for another 2-3 days then starts all over.  It was suggested that the WFBS was the issue so I temporarily shutdown the services on the server and sure enough all works well again.


And here's a 2nd issue related to the WFBS.  When it is running on the server the Activesync phone clients do not get updated email on their phones unless their Windows XP/Outlook client gets them.  It's as if the phone syncs with the Outlook and only then (and no these phones were NOT set up with a tether to the client and set up that way). 


I uninstalled then completely reinstalled the WFBS 6.1 (including the SP).  It corrected the first 3007 issues but then the 2nd issue appeared.  Now after a few more days the 3007's are coming up again with email stopping.  I shut down the Trend services and all works fine.


What is going on?

Re: Very Strange Errors in WFBS6


This could be resolved by enabling the Virus RealTime Scanning and this was a limitation for Exchange 2003.  This is further explained in Microsoft's website:;en-us;827615


Try to perform the following and see if it helps resolve the issue:


a. Enable RealTime Virus Scanning from the Web Console (MSA Configuration Page)

b. Kindly verify the following registry keys on your Exchange Server:

Note: Please backup your registry before doing any of the steps below.

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\<Server Name>\Private-\

    Make sure every Database has the value = 1:


c.  Check and change these values in the registry the same as below:
    [HKEY_LOCAL_MACHINE\SOFTWARE\TrendMicro\ScanMail for Exchange\CurrentVersion]
d.  Check and change these values in the registry the same as below:


e.  Open [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\VirusScan]
    "ReloadNow" and set the value to “1”.


f.  Restart MSA Master service. Run a manual scan preferrably done over the weekend.
g.  Sync Windows Mobile phones with Exchange, and try to send a test mail
