Leeware, then perhaps you can tell the rest of the community with this on-going problem what configuration changes are necessary. Every suggestion in this forum has resulted in no-change for others as well as myself. Changing OS does correct the problem. I tried changing to win2003server on one of the other systems running xppro and sure enough, it started uploading files. So, I guess what I'm saying is:

If you are sharing files, and no one is uploading from you, you have a problem, not that they don't want your files but the problem is on your end not theirs. Obviously, it shows them requesting files from you and their trasnfer gets interrupted after 3-5 seconds. So they want your files, but your OS is interrupting the transfer.

Now, Leeware, would you be so kind to tell us what configuration would correct this?
