File sharing

This is what I did to share a directory with the nework users. I went to control pannel and clicked the server icon to start the the server service so that I see the share tab on the directories that I want to share. When I did this I recieved errormessage " System error 1130 has occured...Not enough server storage is available to process this command." It gave me the same error message when typed "net start server" from the command prompt....Do u have any idea about this?....Thank you,
