The normal way to go is this: Cli.DNSLookUp(HostName); Then in CliDNSLookupDone: if Error <> 0 then begin // Check error, log it do whatever and Exit Exit; end; Assign the returned IP address here, fill in the Port and the Proto and call Connect; DNSLookupDone will call immediatily if DNSLookup is called with an IP address, so you can use this approacht always. --- Rgds, Wilfried http://www.mestdagh.biz Friday, July 15, 2005, 12:50, [EMAIL PROTECTED] wrote: > Thanks for the replies so far. > I have sent a "debug" version of my > software to the guy using it (regretfull I can't access the VPN from > here ...) and he just returned me the result, which is not very > helpful. > When I issue a "CliSocket->Connect()", the state changes from > 8 to 3 and after aprpox. 3 seconds (according to the log-file entries) > back to 8.
