Authentication failed --- Why all of a sudden?

[txstoby]

I was out of the country for over a week and did not access any of the computers on my network.  When I get back I log in to comp 1 and attempt to access compt 2 remotely.  I get authentication failed even though nothing has changed.  I uninstalled TV on the computer that I have manual access to but I still get the same error message.  What should I do next?

Now I am getting authentication rejected.  What gives?

Are you really sure that you are using the correct credentials (ie passwords)
