Exchange 2003 Log Checkpoint File has Dissapeared for an Exchange Storage Group

The E00.chk file is missing in one of my Exchange Storage group's Transaction Log folder.  Is there anyway to recover or regenerate this file?

It should just create a new file?
Is the database not mounting? If not you will need to run eseutil /p followed by ISINTEG see here for more info on how to run these tools: http://www.msexchange.org/tutorials/Exchange-ISINTEG-ESEUTIL.html

It should creat a new e00.chk file but make sure firts take a complete backup all log file.
Aftre that rename a e00.log file to e00.chk and try to mount the Store.

it is also possible to replay the log files into the database manually using the ESEUTIL tool. This can be achieved using the /R option for soft Recovery.
ESEUTIL /r enn /L[path to log files] /s[path to checkpoint file] /d[path to database file] /i

Example: ESEUTIL /r e01 /Lf:\mdbdata /sc:\exchsrvr\mdbdata /dg:\mdbdata /i
You can also try without checkpoint file to RAN soft recovery.
Exam:ESEUTIL /r e01 /Lf:\mdbdata /dg:\mdbdata /i

Thank you for your help. I was able to repair the corruption in the store using eseutil /r.  I was able to backup both storage groups successfully after the repair, which cleared old transaction logs. But in the log folder for one of my storage groups the Checkpoint file is missing so will have to try SatyaPathak's fix tonight of renaming an e00.log file to e00.chk.  The stores in the storage group are mounted and working currently but have no checkpoint file in the log folder.

After researching the issue further before trying to rename the E00.log file, I found that the system path location was different than the transaction log file location for this Storage Group.  This is why the E00.chk file was missing in the transaction log folder.  Just to be on the safe side I dismounted all the stores in the Storage Group in question.   I Right-clicked the Storage Group and then chose properties. Then I changed the location of the "System path location" to the same path as the Transaction Logs and the checkpoint file is now in the proper location.
The checkpoint file was not missing it was in a different location than the transaction log folder.
