server 2003 exchange loosing sync

we have a server that is used for active directory and exchange that is having sync issues regularly.  We are running server 2003 for the OS and exchange server 2003 is installed on this server.  

Almost every day we are having to restart the exchange services in order for our clients to connect.

Errors we receive during this time:

If the logical size of this database is not reduced to less than the maximum size limit, this database will be dismounted the next time a database size check is performed

Please advise as the issue will not stop

Hi, what other event you are currently getting now?

Did you restart the Microsoft System Attendant Service after you changed the value?

Actually this is for Exchange 2003:

I strongly recommend you to set the database to the 75GB ( if your Hard disk has enough room) now itself and keep an eye on database and logs.

Hope that helps :)
