Hi We are using Exchange 2003 server and have been getting the following error message in the log. When this happens we need to restart the server to get the exchange services back. "No database session was available to satisfy a request on database "First Storage Group\Mailbox Store". The number of sessions configured via the Active Directory attribute msExchESEParamMaxSessions on the storage group may be set too low for the level of activity on this storage group. The current value for this parameter is 149. Can some guide me what to do to resolve this problem.
