  • MDBDATA 52 GB log files ..Help needed

    Hello , I have a problem with exchange server 2000 on windows 2000 server sp4 , the hard drive is 160 GB divided into 2 equal partitions , on drive C i have the exchange installation and database , to be honest the server is not being take care of , in terms of regular maintenance and backup , a few days ago i noticed that the free space on drive C is only 1 gb , and by some troubleshooting i found that MDBDATA folder has a 52 GB log files , searching on this great forum i found alot of helpful articles , i tried to do the online backup which was supposed to purge the log files , but the first time it took like 30 minutes and then the backup windows has become non responsive , i was monitoring the size of the file of backup and it was 3 gb , i left the backup process like this for 3 hours , and by checking again the backup file , it's the same 3 gb file , so i had to terminate the process by force , i was backing up to another server through network , now i choosed to backup on drive D from the same server which had like 50 gb free space , but when i start it just takes one second and terminate the backup , by checking the report it says "Backup started on 10/1/2009 at 8:05 PM.
    WARNING: Portions of "\Mailbox Store (server-name)" cannot be read. The backed up data is corrupt or incomplete.
    This file will not restore correctly.
    WARNING: Portions of "\Log Files" cannot be read. The backed up data is corrupt or incomplete.
    This file will not restore correctly"

    all what i want to do is to get rid of these huge log files and gain more space , i read about the offline backup but it's not clear for me if i will be able to delete these log files manually after the offline backup or not , also i read in some articles that i should have a fair space on drive C to make the online backup , a space that is equal and more by 10 % than the database and log files size , need help please

    also i can't seem to find the file eseutil.exe on the server to check for the DB integrity , any help where can i get it .

    thanks .

    If you want to remove the logs, then follow this KB article very carefully.
    http://support.microsoft.com/default.aspx/kb/240145

    Do not skip through it, read it twice and make sure you are very clear on what you are doing, as you have no backup.

    Once completed you need to resolve your backup issues, because that is the only way to keep the logs down.

    If you are never going to backup Exchange then enable circular logging.

        Hello again , i read the article very well , and was planning to start fixing the problem today , but something horrible happened , the Exchange server is not in my city , it's in another city , i connect to it remotely , anyway , this morning i couldn't login remotely to the server so i called that HQ to make sure what is happening and they told me that the win2k on that server is not loading !!

        it gives this error message :

        Windows could not start because the following file is missing or corrupt:\WINNT\SYSTEM32\CONFIG\SYSTEMced

        i had someone there to put the win2k cd and boot to the recovery console , i used a fix from Microsoft shown in this article http://support.microsoft.com/kb/269075

        by copying c:\winnt\repair\system to c:\winnt\system32\config after renaming system to system.old and system.alt to systemalt.old inside system32/config

        after this the windows was loading , i thought the problem got fixed , but a blue screen appeared that saying :

        c0000221 {bad image checksum} the image ole 32.dll is possibly corrupt

        i don't know what to do now , is it possible to reinstall windows again over the working one without messing up with the configuration? just as a repair ?

        what are my chances ? what if this windows installation got lost ? will it be easy to take the database from the old hdd and move it to a new server with the same name ?

        thanks

          You need to get someone to look at the server carefully - it is not something that I think is best advised with on a forum. If the OS was still supported I would tell you to call Microsoft. Unfortunately that is out of the question. You need to get an experienced consultant to look at the server to repair it. If you aren't careful you will lose the configuration of the server and may have to DR Exchange.

            eseutil.exe is supplied with Exchange 2003 and the management tools. It is usually found in c:\Exchsrvr\Bin or c:\Program files\exchsrvr\bin.

            Ideally, you should add the above path to the PATH environment variable using the System Control Panel, Advanced, Environment Variables to make it easier to find it.

              ok , just hopeing for the best and preparing for the worst , here is the deal , in our company we don't really depend too much on the domain , i mean in terms of logging to the pc's by users , the servers are there to hold the sales programs and database , all user's pcs are in "workgroup " , when a domain controller is offline for any reason , nobody is affected , for the exchange , users have the emails on their pc's , at least for the last week , except the emails in the down time , what i need to ask , what if we couldn't fix this windows installation , and we had to reinstall a new exchange ,can we give the new server the same ip address "internal & external " as it was for the old exchange ? configuring the exchange will be done by our ISP the one in charge for the email forwarding , for the AD , i think creating the users again won't take a lot of time (apporx 100 users ) , what do you think . thanks

                  First I would do is backup the offline c:\Program Files\Exchsrvr\MDBDATA folder using a Linux Live CD ( ERD Commander, BARTPE, PE Builder, MiniPE, etc...).

                  Second, run CHKDSK /r from the System Recovery to check and repair bad sectors.

                  If that doesn't work, then you will need to repair the installation by using the OS CD.

                  If you have to reinstall the OS, make sure you install the same OS version and name the machine the same name.

                  You may have a chance at recovering Exchange.

                  Just a tip for the next Exchange install, do not install Exchange on the primary partition C:\.
