Needed to add a user to the local administrators on 16 citrix servers, below is the code if you need it.

psexec @servers.txt cmd /c “net localgroup Administrators /add domainusername”

this doesnt work with multiple usernames at one time.

get psexec here: www.sysinternals.com

servers.txt is a text file containing a list of servers, i.e:

server1

server2

etc
