First of all we know you are using Outlook Express to
read your newsgroups we can see that in your headers..
Do you still see the old messages with "Show All"
Before using RESET (under properties)you might try the following.
Right click on the newsgroup and try "Catch up"
If that doesn't work take your OE6 offline, then compress your
OE files. File, Folder, Compact All Folders
It is important that you be offline in OE when you do this or risk losing
OE databases. (file, workoffline)
if that doesn't work, rather than RESET of this newsgroup,
I would set up an account connecting directly
to the Microsoft Server. As was pointed out you are not connected
directly look at your Path in your headers (Ctrl+F3) from one of
your posts.
