Unable to Connect to SQL Server

this just started happening to me too.

I originally connected to our dev server, and did a bunch of stuff.

The minute I tried to connect to another server, this error started happening.

Now, I cannot connect to any server, not even the original one I have been working with for weeks.

Something got corrupted somewhere.

I have attached my trace files

This is probably not a permissions problem, or an allow remote connections problem.

I did not see a way to attach files, so I am only able to past the data from the first trace file. 

Thanks,

Michael
