dun worry its not shared ont he network unless u actually enable it
for ur piece of mind u can disable it by copying following code in a file
save it with .reg extenstion
and run it
Code:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa]
"restrictanonymous"=dword:00000001
"restrictanonymoussam"=dword:00000001
"everyoneincludesanonymous"=dword:00000000
