You can search for managed computers from an external comma, semicolon, colon, or tab-delimited text file. You choose the computer data in the text file to match to the managed computers. A temporary group is created with the resulting computers.
To find computers by file
Expand Computers.
Right-click All Computers and choose Find Computers > Find Computers by File.
Browse for the text file you want to use.
In the Find Computers by File dialog box, make the appropriate selections, and click OK. A temporary group is created.
Right-click the Temporary Group name to make the group a permanent group or to search the list of computers.
