VNC Error

[Roy Park]

I am using VNC on a Windows 2003 Server.  I am trying to access it from a
Windows XP computer.  I was using a dns alias and was working fine for the
last 6 months.  However, I started recieving this error and have not been
able to access my server.

"unable to resolve host by name:  The requested name is valid and was found
in the database, but it does not have the correct associated data being
resolved for. (11004)"

I appreciate any help I can get.  Thank you.
