Interesting question. In researching this, I was amazed how many posts I found stating that SQL Server needed to be restarted after changing a thesaurus file.
aahh!!! As soon as I saw the Restart SQL server option, I jumped on it as the answer with a pride only known to a dumbass in a hurry!!!
I guess it doesn't matter how many times I restarted the server if I keep editing the wrong file.. does it?
If I can answer a question then anyone can answer it..trying to reverse the logic..
