Thanks I visited the GRC site and this is what the report stated:
Attempting connection to your computer. . .
Shields UP! is now attempting to contact the Hidden Internet Server
within your PC. It is likely that no one has told you that your own personal
computer may now be functioning as an Internet Server with neither your
knowledge nor your permission. And that it may be serving up all or many of
your personal files for reading, writing, modification and even deletion by
anyone, anywhere, on the Internet!
Your Internet port 139 does not appear to exist!
One or more ports on this system are operating in FULL STEALTH MODE!
Standard Internet behaviour requires port connection attempts to be answered
with a success or refusal response. Therefore, only an attempt to connect to
a nonexistent computer results in no response of either kind. But YOUR
computer has DELIBERATELY CHOSEN NOT TO RESPOND (that's very cool!) which
represents advanced computer and port stealthing capabilities. A machine
configured in this fashion is well hardened to Internet NetBIOS attack and
intrusion.
Unable to connect with NetBIOS to your computer.
All attempts to get any information from your computer have FAILED.
(This is very uncommon for a Windows networking-based PC.) Relative to
vulnerabilities from Windows networking, this computer appears to be VERY
SECURE since it is NOT exposing ANY of its internal NetBIOS networking
protocol over the Internet.
everything looks fine as you said it might be except for the first paragraph
about my pc acting as an internet server. what do you think. really
helpful responses by the way, I appreciate it.
