Weird Problem with Exchange 2003 SP2 GAL

I have a very weird thing happening with Exchnage 2003 SP2 and AD. Recently some users are not showing in the GAL. Some of these users have been in AD for years. I notice that if I run ADSI edit and look at one of the users, the showinaddressbook attribute is not set and then when I look again seconds later it is set.
This replicates in the GAL with the user being there one second and gone the next. I can create new users that work OK.

Any ideas?

Is there any applications/Script which makes use of GAL?
Are you using any software or script for GAL synchronization?

Turn on diagnostic logging for following and see if there any error.
MSExchangeAL \ LDAP Operations
MSExchangeAL \ Address List Synchronization
MSExchangeSA \ Proxy Generation

Also just remove the Automatically Update Email Addresses option from user email addresses tab and test it the issue persists or not.

I am not aware of any apps or scripts using the GAL, or any other software synchronisation.

We have turned those diagnostices on and have not yet seen any errors. I have manually updates the RUS and rebuilt the OAB and still no errors.

I have just turned off the check box as asked the users are stll appearing and disappearing from the GAL i can see this when using OWA and searching for them.

It looks as if a restart of the DC may have resolved this. I will monitor over the next few days and report back.
