RE: IIS Logfile

Without knowing exactly what your severs are doing its hard to say
(unless you are a bank)

However, you will probably find that they are simply running scripts
against your system and when they can't get anywhere they'll give in.

Just keep an eye on things

O and patch everything till your fingers bleed!

Thanks to all of you for replying.

This log file is getting weirder. Here are more strange entries:

2004-10-26 01:04:22 202.38.216.127 - W3SVC1 FILESERVER xxx.xxx.xxx.xxx
80 GET
/scripts/nsiislog.dll - 401 5 0 - - -
2004-10-26 02:54:32 130.235.160.66 - W3SVC1 FILESERVER xxx.xxx.xxx.xxx
80 GET
/M83A - 401 5 0 - - -
2004-10-26 02:54:32 130.235.160.66 - W3SVC1 FILESERVER xxx.xxx.xxx.xxx
80

80 GET
/scripts/nsiislog.dll - 401 5 0 xxx.xxx.xxx.xxx - -

I am located in the ass of the world (South America) and I don't
understand why
some chinesse and sweden people should be interested on my net? (those
IPs are
from that places)

Like you say, the 401 code means an authorization failure, but, what is
they
trying to do?

Thanks in advance...
