 Dim un As String = "user-tplp-support" 
 Dim s As New DirectoryServices.DirectorySearcher(u, "(nisNetgroupTriple=(," + un + ",))") 
 Dim r As DirectoryServices.SearchResultCollection = s.FindAll 
 Catch ex As Exception 
 Return ex.ToString

 is throwing exception at FindAll 
 
 System.Runtime.InteropServices.COMException (0x8007203A): The server is not operational.

Hello, This error is quite common and may occur for a variety of different reasons. The most obvious cause is that the server you were trying to contact might actually be down, it may be blocked by a network firewall, or it might not exist at all. Confirm that the server is online and can be reached from the job server processing these jobs. Trevor
