Repairing the SRUDB.dat
When you run SrumECmd, you will likely encounter an error message that states the file is dirty.
Command line: -d M:\Forensics\SrumECmdTest\tout -k --csv M:\Forensics\SrumECmdTest\mout\SystemActivity
Found SRUM database file 'M:\Forensics\SrumECmdTest\tout\C\Windows\System32\SRU\SRUDB.dat'!
Found SOFTWARE hive 'M:\Forensics\SrumECmdTest\tout\C\Windows\System32\config\software'!
Processing 'M:\Forensics\SrumECmdTest\tout\C\Windows\System32\SRU\SRUDB.dat'...
Error processing file! Message: Object reference not set to an instance of an object..
This almost always means the database is dirty and must be repaired. This can be verified by running 'esentutl.exe /mh SRUDB.dat' and examining the 'State' property
If the database is dirty, **make a copy of your files**, ensure all files in the directory are not Read-only, open a PowerShell session as an admin, and repair by using the following commands (change directories to the location of SRUDB.dat first):
'esentutl.exe /r sru /i'
'esentutl.exe /p SRUDB.dat'
Executed 1 processor in 0.9046 seconds
Total execution time: 6.5490 seconds
Follow these steps to repair the SRUDB.dat
so you can run SrumECmd.exe again. First, follow the steps SrumECmd provides:
-
Make a copy of the files within the
.\SRU
directory -
Ensure the
.\SRU
directory itself is not Read Only. This can be done by right clicking on the directory itself, Properties, and unchecking Read Only if it is checked:
-
Open a PowerShell session as an Administrator in the directory where your copied files reside
-
Execute this command within the PowerShell Admin session:
esentutl.exe /r sru /i
-
Execute this command within the PowerShell Admin session:
esentutl.exe /p SRUDB.dat
- Try running SrumECmd again against the location where these repaired files reside:
- Examine output in Timeline Explorer!
