Hi,
Verisign's SiteFinder service also breaks many of the standard Windows
networking utilities by providing misleading error messages, temporary
lockups, and incorrect status information.
For example, referencing a UNC path with a misspelled domain name with
SiteFinder in the picture gives an incorrect error message and hangs a
command prompt window for about 30 seconds:
C:\work\sitefinder>dir \\sdkfasdlfkasdlfkasdk.com\drivec
Access is denied.
The correct error message is displayed instantly if SiteFinder is out of
the picture:
C:\work\sitefinder>dir \\sdkfasdlfkasdlfkasdk.us\drivec
The network path was not found.
The correct error message for a misspelled domain name in the Windows
FTP utility is:
C:\work\sitefinder>ftp ftp.asdklsdfjaskdfjasdfjasdjfasdfj.us
Unknown host ftp.asdklsdfjaskdfjasdfjasdjfasdfj.us.
With SiteFinder, the FTP utility now provides a useless error message:
C:\work\sitefinder>ftp ftp.asdklsdfjaskdfjasdfjasdjfasdfj.com
> ftp: connect :Unknown error number
The PING utility gives incorrect results for misspelled domain names:
[Incorrect]
C:\work\sitefinder>ping www.sdfjasdfjaskldfjasdfjas.com
Pinging www.sdfjasdfjaskldfjasdfjas.com [64.94.110.11]
with 32 bytes of data:
Ping statistics for 64.94.110.11:
Packets: Sent = 1, Received = 0, Lost = 1 (100% loss),
[Correct]
C:\work\sitefinder>ping www.sdfjasdfjaskldfjasdfjas.us
Ping request could not find host www.sdfjasdfjaskldfjasdfjas.us.
Please check the name and try again.
Ditto for tracert:
[Incorrect]
C:\work\sitefinder>tracert www.asdfjasdkfjasfjasdj.com
Tracing route to www.asdfjasdkfjasfjasdj.com [64.94.110.11]

...
[Correct]
C:\work\sitefinder>tracert www.asdfjasdkfjasfjasdj.us
Unable to resolve target system name www.asdfjasdkfjasfjasdj.us.
