Subject: How Verisign's SiteFinder service breaks Windows networking utilities

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]
   over a maximum of 30 hops:

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