After listening to Larry’s excellent technical segment on dumping the event logs from a large list of computers, I decided to try it out on my own. If you missed the technical segment, you can find the notes here. To do my own testing I needed to start with a large list of computers. For my list, I want to have the names of every computer in the domain. So I turned to “dsquery computer ” to get a list of all computers.
C:\WINDOWS> dsquery computer
"CN=CONTROLER1,OU=Domain Controllers,DC=subdomain,DC=domain,DC=com"

BLA BLA BLA… Truncated

"CN=WORKSTATION1,OU=ORGUNIT1,OU=OrgUnit2,OU=OrgUnit3,DC=Subdomain,
DC=Domain,DC=com"

BLA BLA BLA… Truncated again

The length of the results changes because of the variable number of subdomains, but fortunetly for us the workstation name is always the first part of the string. It is always between the CN= and the first comma. We can strip out the workstation name with the “DELIMS” and “TOKENS” option of the FOR loop. Also, by default DSQUERY will only return the first 100 results. This can be changed using the “-LIMIT” option. Setting the LIMIT to 0 returns all result. For now lets check our output looking at only two entries.

C:\WINDOWS>for /F "delims=, tokens=1" %i in ('dsquery computer -limit 2') do echo %i

C:\WINDOWS>echo "CN=WORKSTATION2
"CN=WORKSTATION2

We are almost there. I need to strip the first 4 characters of the line. For this I stole a page or two from Ed Skoudis’ play book. We can strip the first four characters with the SET command using the expression variable = %variable:~4%. But, since we are in a FOR loop we have to turn on delayed variable expansion and use ! instead of %.

C:\WINDOWS>cmd.exe /v:on /c "for /F "delims=, tokens=1" %i in
('dsquery computer -limit 2') do set name=%i & set name=!name:~4! & echo !name!"
