Sometimes it’s the little things that get you when working on client’s servers and workstations remotely.
You need a Dell service tag that doesn’t show up in the usual places such as “My Computer” -> “Properties” or can’t be detected by the Dell web based support ( ActiveX if I recall correctly). What do you do? Try this! Open a console window and type in “wmic bios get serialnumber” at the prompt. Your Dell service tag will be returned for you viewing pleasure.
A simple solution to a sometimes not so simple problem.
