Re: 19991103: lost mcidas data at NM State

Dave,

Now is the time to contact your network folks or your ISP about this
problem. It appears to be a network problem, maybe a router configuration
was changed etc. Since your are the customer, the network vendor/folks
have to open a trouble ticket or track down the problem.
