Hello!

I'm using Indy9 and BCB6 Enterprise, and I'm trying to get the name of the 
computer that's connected. In the OnConnect event of TIdTCPServer, I've the 
following code:

  sIP = pAThread->Connection->Socket->Binding->PeerIP;
  sCompName = GStack->WSGetHostByAddr(sIP);

This works fine on all the machines I've tried it on - except a Windows 2000 
computer, where an exception is thrown during WSGetHostByAddr(). Has anyone 
any idea about what would cause this call to fail, and what I can do about 
it?

I've checked the sIP variable, and it is correct; but WSGetHostByAddr() 
still fails.

Thanks,

- James
