Hi!
I have a problem with
System.Net.Dns.GetHostByAddress(ls_Request.UserHos tAddress()).HostName
Usually the call GetHostByAddress returns the correct hostname of the
client, but sometimes I get a hostname like _CERDR1342B88E.
Why? The clients are running under Windows CE.NET 4.1...

What happens if you probe a ip address that returns such a name op port 445?
Is it open? If so, the computername is returned and not the hostname.
Someone with more knowledge of the tcp/ip system could clear this out.

I looked up the computername on the windows ce machines, but the
computername is the one we set initialy (not _CERDR1342B88E)! But the
call System.Net.Dns.GetHostByAddress returns _CERDR1342B88E. I don't
know what the call System.Net.Dns.GetHostByAddress exactly does, but
it does not seem to be right.
Since the hostname is not really _CERDR1342B88E, i think a probe on
port 445 does not make sense...
