Try using TFTP server from SolarWinds. It's free to download.

http://www.solarwinds.com/products/freetools/

Make sure too that you have unzipped and placed all of the correct files in the root directory of the TFTP server.

•OS79XX.TXT-This file will now always contain the universal application loader image.

•P003.........bin-Nonsecure universal application loader for upgrades from pre-5.x images.

•P003.........sbn-Secure universal application loader for upgrades from images 5.x or later.

•P0a3.........loads-File that contains the universal application loader and application image, where "a" represents the protocol of the application image loads file: 0 for SCCP, S for SIP, and M for MGCP.

•P0a3.........sb2-Application firmware image, where "a" represents the application firmware image: 0 for SCCP, S for SIP, and M for MGCP.
