Need to reboot Exchange 2003 server daily in order for Actice Sync to work
I have one Exchange 2003 mailbox server and one Exchange 2003 front end server both running on windows 2003 standard. Active Sync enabled to allow smart phones to sync. After we switched to Office 2010 in Jan, users started to get "Account Error" periodically on their smart phones and were not able to sync until I reboot the exchange mailbox server. it's getting to a point now I have to reboot the mailbox server daily. Same Users were not affected when using Outlook or Outlook Web Access when not able to sync via smart phones. No errors were logged in either application or system event log on both exchange servers.
Anyone has any insight on what might happen and how to fix this? Thank you.

Have a look at the capacity of your edb files as there is a sub 100 gb limitation on xch 2003. I know that exchange does housekeeping over night which compresses the edb files.

My db size is about 65gb, the limit is 75 gb.
Does a restart of IIS correct the issue (versus rebooting the server)?
ASKER
no. I must reboot the mailbox server. I tried only restarting the exchange services on the mailbox server, that only fixed it for about an hour, then users would see the same errors again on their smart phones. Thank you.
Can you please set the Exchange Application Pool to recycle every 24 hours (please see the following article for details of how to achieve this):

Once set - please monitor for 24-48 hours and see if the problem goes away.

Can you please send me the IIS logs during sync error.

ash007,
I will wait unit I have problem sync again, then upload the log. Thanks.

Have you set the Exchange Application Pool to recycle daily yet?

alanhardisty,
no. Since I only need to reboot the mailbox server, not the front-end server that's running IIS, I don't think it's the problem with IIS. Do you think I should still try it? Thank you.

It won't harm anything to try it and might improve the situation for you.
Worst case, you stop recycling the pool if it doesn't do anything.

Here is what I found: I moved my mailbox to our standby server (Exchange2) last Thursday, so far I haven't had any sync errors. However, I already had to reboot my regular mailbox server (Exchange1) twice since last thursday. I don't see any http errors on the front end server nor on Exchange 1 when users not able to sync.
Could it be some problems with the mailbox store on Exchange1? Is there a utility I should run on the mailbox to check it out? Thank you.

It sounds almost like a DNS issue.
You can run the Exchange 2003 BPA to see if it highlights anything:

alanhardisty,
How DNS would contribute to this? Why a reboot would fix it? Thanks.

I ran BPA tool, no obvious issues found. Thanks.
If one server cannot find the other then DNS might be causing the problems.
If you reboot the server, you restart the DNS service on it and sometimes just restarting the DNS server / service can fix the issues.
Can you post the ipconfig output for both servers please.

ASKER
I am able to ping each other using either ip or server name, so there shouldn't be a problem with DNS. DNS is running running either on my exchange front-end server or the mailbox server.
ASKER
I meant DNS is NOT running on both servers. Thanks.
Not sure I have any other ideas. Sorry.
