Adsutil.vbs is a versatile and useful tool to administer IIS 6.0 servers. But did you know there is a remote server command-line parameter? With this you can use Adsutil.vbs remotely.
-s:IIS 6.0 Remote management with adsutil.vbs
adsutil.vbs to automate tasks on local and remote servers
You can administer remote IIS 6.0 webservers with this parameter setting. Very convenient in a loop:
for /f %i in (server_list.txt)
do @cscript c:\Inetpub\AdminScripts\Adsutil.vbs
GET W3SVC/1/ROOT/AppPoolId -s:%i
You can find adsutil.vbs (and metaacl.vbs) as download here. Save both .txt files as .vbs.
