Query distibution groups and their members

Here is the script that will export all distribution groups in the file groups.txt and then will put these groups and their members in the file membership.txt:

dsquery * forestroot -filter "(samAccountType=268435457)" -limit 0 > groups.txt
for /f "tokens=*" %%g in (groups.txt) do @echo %%g >>membership.txt && echo Members: >>membership.txt && dsget group %%g -members -expand >>membership.txt && echo **************************************** >>membership.txt

If you want to do a query on security groups, or on distribution groups that have managers assigned and then list their members, please see my other posts from the Scripts categories called Distribution lists and managers and Security and distribution groups and easily modify the upper script.
