add or remove program query

Hi,

i want to find out what are all the installed softwares in a server. for example if there are 150 servers connected in a domain, its a difficult job to log in to the 150 servers and find out the installed using add or remove program.

instead,is there a batch file to pull the details of a software installed in 150 servers automatically to a excel sheet?

thanks in advance.
