Computer 1: -

Well i haven't noticed this before, after seeing your question i went back to check the log and within this week its coming contineously.

If you are talking about computer 1 nopes its not a new machine and its not been re-configured.

I have updated the server 2 days ago and even today and couldnot find any hotfix or update so far missing the server is uptodate.

Now that you have mentioned let me checkout COMPUTER 1 and see if i can find something over there.

But the issues is not at a particular user end its like my Domain is there but new users or computers can't join in.
