Problem to Log On

[Jim Fazzone]

That error is caused by either a duplicate name in the
active directory scheme, or an incorrect address on your
side. Log in to the machine as the local admin, and make
sure that you're resolving a proper address. Then, try
leaving and re-joining the domain. If you are denied,
make sure that a duplicate name of the machine does not
appear on the network.

Good luck!

This could be a break in the Winsock LSP chain, as well:
