Hello
Depends if you are using Windows auth to secure a web site
This configuraiton will prompt the user for a login when
accessing web site
if there is no pompt when accessing your web site, username
is "anonymous", i.e. IUSR_MACHINENAME where MACHINENAME
is the name of your server
This user is logged in IIS log file, ensure cs-username
is checked in IIS logging, then open the log file
Another way to extract this user from HTTP commnication
is to capture 1 HTTP request from the client and read the
HTTP header "Authorization"
if the first string you see is "Basic", you can extract
username and password from the second string which
is username:password encoded in base64
So the complete header for someuser / somepass would be :
Authorization: Basic c29tZXVzZXI6c29tZXBhc3M=
use base64 tools to decode it :

Have a nice day

Objet : How to find the login name of a user accessing my website
I was wondering if anyone could help me how I can find out the windows login
of the user, accessing my website. I think i read it somewhere that it gets
passed as a header information but i am not sure. If anyone of you guys can
help me with this, i will really appreciate it.
thanks
