AEN007 Posted December 3, 2009 Share Posted December 3, 2009 3December2009Greetings.I have three (3) XP laptops & would like to be able to useintranet time sync utilities but at the moment cannot at allbecause at the moment I can not PING at all -with one minor exception. I have seemingly lost the abilityto PING any NICs.Recently I could PING between laptop G & laptop T - both directions.I could also PING between laptop i & laptop T - both directions.I can no longer PING amongst the latops except when I activatethe Direct Cable Parallel Port Connection between T & i.Laptops T & i both have XPPro. Laptop G has XPHome.I do not use Simple File Sharing on laptops T & i.I network the laptops with varying NICs depending onwhat type of internet connections I have to use.At the moment I have two ethernet connections -one on G & one on i. I always connect G & iwith USB bridge/network cable. Right now I use a pcmcia wLAN NICon laptop T to connect T to G & i, so I have a redundant connectionbetween G & i.1) Is there any way to connect T with I & G via wlanbut not also connect I & G via the ad hoc connections?It seems to me that the problem is not the free ZoneAlarm firewall.Until this week I could make the above PING connectionsbetween G & T and T & i. I have never (not yet anyway)been able to PING over the USB bridge/network cablebetween G & i. Because T is almost never connected to the internet,I uninstalled (& then reinstalled) ZoneAlarm on T; however,uninstalling ZoneAlarm did not allowing any PINGing to or from T.Activating the DCPPC between I & T for some unknown reasonenables pinging between I & T over the DCPPC.XP assigns the DCPPCs a subnet mask of 255.255.255.255,which I thought was "illegal" ...I could go on & on with details, but for now I'll just hope that someonewill reply & eventually help me restore PINGing over my Ad Hoc LAN.2) I cannot start remoteaccess on I; however,I can start remoteaccess on T.G does not list remoteaccess as a service option.I & T have parallel & serial ports. G does not.At a minimum I would like to "ping" between I & T.T is usually never connected to the internet,so I would like to use intranet time sync utilitiesbetween I & T.Enabling the direct cable / parallel port connectionbetween I & T (I as guest & T as host) allowspinging between the I & T DCPPC IP addresses(but not the wLAN IP addresses ...).Most of my LAN traffic goes from I to G & I to T,so I set up the DCPPC with T as host.Previously I could not set up a guest DCPPC on Tbut could start remoteaccess on I. Now I cannotstart remoteaccess on I but yesterday was ableto setup a guest DCPPC on T. I could use intranettime sync between I & T when a DCPPC would be active.I cannot, however, have the DCPPC where T is hostbecause all traffic from I would go over not onlythe wLAN connection but also the DCPPC,which causes T CPU usage to go to 100%.If I could (once again) start remoteaccess on I,then I could activate T as a guest. Then there would bean active DCPPC but traffic from I to T would only goover the wLAN connection. I found/tried 2 proposedsolutions to the remoteaccess "won't start" problem,but neither worked for me.I tried the Winsock reset procedures -at first on the 2 XP-Pro laptops (T & I).Immediately afterwards I had partial ping success.The partial ping success lasted about 30 minutes.After the XPP winsock resets, I could ping all the wlanconnections but still not the usbnetz connections.I had to make some nic readjustments which maybe killedthe partial ping success. I don't now why the reset on the2 XPP laptops (I & T) allowed pinging the untouchedXPH laptop (G). It might be that installing the usbnetzconnections somehow impedes the pinging. If so, I don'tknow why. The "networking" works fine. Each connectionreads & writes both directions without problems.The XP "Search for Computers" finds all computers, butI still cannot ping any connections.Any helpful replies/insights appreciated.Thank you.Regards,AENÆP.S.:The PING error message is almost always,"Request timed out" not "Destination host unreachable" ...For some unknown reason today I successfully pinged(for the first time ever) to a USBnetz IP address -however, only one way. For some unknown reasonI could not ping back to the other USBnetz address ...No other pinging (except the DCPPC described already) works ...Any helpful replies/insights appreciated.Thank you.Regards,AENÆ Link to comment Share on other sites More sharing options...
AEN007 Posted December 5, 2009 Author Share Posted December 5, 2009 5December2009Greetings.I am VERY HAPPY & RELIEVED to say thatI have finally actualy hacked my way throughthis Network/Ping labyrinth and now seem to havea fully functioning PINGABLE XP Ad Hoc LAN.Regards,AENÆ Link to comment Share on other sites More sharing options...
