Hi Guys, Hope one of you may be able to kindly offer a few suggestions to the below We have a Windows 2003 SBS SP2 Running on a HP ML350 G5 Server. We purchased this about 4 months ago and transfered all data including the exchange data from our old SBS 2000 server. Our issues are with Exchange 2003 (SP2) Theissue is that we cannot seem to dismount the Mail or Public or public store without the process stopping at 66% this then causes the server to eventually lock up and have to be power cycled. When the server then comes up (we do not mount the stores automatically) we then have to repair the edb/stm files for bot mail and public before placing them back on line exchange them behaves fine until the next time it has to shutdown i.e. power failure etc. Last Month we finally made a decision to exmerge all the data out of the 2 stores and place in PST files and create a brand new mail and public store hopeing this would be the end of our issues, but NO we still have the problem of the stores will not dismount without hanging (allbeit they now only take a few minutes to repair as they are so small) We have made sure that our virus checker (CA Etrust 7.1) is not scanning the mdbdata folder. The other issue is that the server grinds to a hault if we let our Backup (Symantec Backup Exec 11d) try and backup the information stores. Apart from this the server runs fine and there is no disk errors in the event logs. Any help on this strange issue would be greatly recvd. Nicenswift

To troubleshoot the store.exe spiking CPU utilization issue, we may need to research the dump files of store.exe at last. Nevertheless, I am not a expert for debugging dump files. If you want this service, youd better to contact our premier CSS service. Typically, we can perform following general troubleshooting steps and then check effects. 1) Firstly, please ensure that you have recent backups of the .edb and .stm files for both mail and public folder store. (I recommend you use Microsoft NTBACKUP)2) Run an offline defrag against the database files. Example: eseutil /d <database_path_and_file_name> /t <temp_database_path_and_file_name> More information: ============ http://technet.microsoft.com/en-us/library/aa998863(EXCHG.80).aspx 3) If the defrag works then our next step is run isinteg -s servername -fix -test alltests. -Jason
