Ok I noticed I have port 139 open again. I was doing port scans on myself because my internet has been real slow lately. Besides I figured well this is a good time to check my own security. I usualy do pretty often. I dont know that much about it, but I look for oddities.

Now a year or so ago I always had port 139 open, and then this summer I reformated my hard drive, and it seemed port 139 wasnt open. I havent noticed it open untill today since then. But exactly what is port 139 used for, and why would it be open?

I'm running the normal applications that I was just a week ago and I didnt have that port open. So whats going on here?

Thanks for any help.
