Workaround Goto sa_pattern.LIST Open the pattern DNS (Shared Library), Note: NOT the "DNS Shared Library" pattern Goto step "Parse the IP DNS Names in EVAL" Replace the old code with new code as showing in demo.png in the attachments of this KB Under "Related Links", click on "Synchronize with MID Servers" OLD CODE : if (nslookup_response.indexOf(\"Name: \") &gt;= 0 ) { var regex = /Name: (\\s+.*)Address:/; rtrn = regex.exec(nslookup_response)[1] //getting the exact Group match of the regex with the index of 1 } else if (nslookup_response.indexOf(\"Name= \") &gt;= 0 ) { var regex = /Name= (\\s+.*)Address:/; rtrn = regex.exec(nslookup_response)[1] //getting the exact Group match of the regex with the index of 1 }

NEW CODE : var regex = /Name(?:=|:)\\s*(.*?)\\s*Address:/; var temp = regex.exec(nslookup_response); rtrn = temp && temp[1];
