Can anyone help me in shareing my scanner on lan for others to use from their PC??

Scanners aren't like printers I'm afraid, they need to have to have a sharing option in their software. Post the make and model of your scanner and we'll let you know.

Another way to share your scanner is using RemoteTwain ( http://www.scanworkssoftware.com/remotetwain.aspx ). It is TWAIN driver so it allows using any TWAIN compliant software and scan from scanner attached to another PC remotely.

Yes definitely I have share my scanner on lan... its a 100 % working now...
