Exchange 2000 M drive disappears and mailbox and public stores can not mount

Last night we applied Exchange SP3 to our Exchange 2000 Enterprise Edition in order to solve public folders not appearing in OWA problem.  Doing tis instantly fixed this problem and the server appeared to be working normally - sending and receiving emails until 10am this morning.  Then all of a sudden - no email access for any users!

M drive has disappeared entirely from Exchange machine and can not mount mailbox or public stores in Exchange Server Manager.  The error that comes up tells us to restart either or both of IIS and Exchange services and try again.  We did this and still the same problem.

A point to note is that last night before applying SP3 (for exchange) we played aroud a little with the HTTP virtual server anonymous login under exchange manager as well as the public folder virtual folder on IIS.  We also added ISUSER_exchange user account to both of these.  I am not sure if this has anyting to do with it or not..

This is an emergency and we would appreciate any help you can give.

The problem is not related with the settings  you change in your HTTP Virtual Server.

M: drive will be back after all the exchange services starts.
So, make sure that the Exchange Information store service is started. (Admin tools-Services) if not, start the service manually.

This usually happens after applying SP3 because the store.exe will increase memory usage and it will not release the memory for other applications.

These was fixed in Post-SP3 Patches Apr 2004 (as i remember) was the latest. Download the post-fix and run it on your exchange server.

cheers!!

Back again - it didn't seem to work.  Still exactly the same problem.

I am currently rebooting the server after installing the post-fixjust in case (it didn't tell me to).

Any ideas?

Thanks

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

Stop antivirus service, and restart the services again.

Again, what message are you getting when you try to mount the mailbox store ?

This is the error message

--------An internal processing error has occurred.  
Try restarting Exchange System Manager or the MS Exchange Information server, or both.

Exchange System manager------

I will try the antivirus stop and then restart the services option.  Will let you know how it goes.

Thanks for staying with me!

cheers

thanks for that...

I have tried these but none of them worked.  However, from the information in them I was able to ascertain that E00.log is not present.  I re-checked the app log and found that the system attempted to move the E00.log file and that is when this problem started.  I looked inside mdbdata folder and the E00.log file is not there - there is however an E00 file that is of the type "recovered file fragments".  

Is there aything I can do to restore the E00.log file and if I do this will it fix the problem do you think?

Thanks

no oif e00.log is not there
then u mover all other log files that is e000001,e000002 etc to different folder and then try to mount.
also see if the information store service is started.

I am afraid you lost your E00.log file. Move the E00.log file from the Quarantine folder to the Exchsrvr\Mdbdata folder or log file folder, and then mount the database.

If you cannot find it then follow the link below
