1. ANDY FLETT’s IP CONFIGURATIONCHECKroutine – ideallyinstalledonPCsBEFOREdespatch,to
enable ittobe used whenapparentlyisolatedfromanetwork,toallow fornetworkproblem
diagnosisindependently.Thisroutine…….
 DETECTS all “installed”Network Adapters
 DISPLAYSany associatedIPAddressesagainstrelative NetworkAdapters,andanyrelevant
messagesabouttheirconfiguration(e.g.Home Networkaddress,VPN Connectionaddress,
APIPAddress)
 TESTS associatedIPAddressesforconnectivityandfunctionality
 No special software required –makesuse of standard IPCONFIGcommand(aslongas the
relevantactive computerpolicyallowsusage of thiscommand)
 Detectedproblems –are explaineddirectly
EXAMPLE 1 = NetworkAdaptersdetected –but none withassignedIPAddresses =NOTETHE
WARNINGSABOUT NOASSOCIATEDIPADDRESSES,and possiblywhattotry to resolve thisproblem
Thisis an example of aFULL NETWORKINGFAILURE,but there maybe nothingwrongwiththe
“networksoftware configuration” oradapters (i.e.the NetworkAdaptersAREdetected ,butthey
may notbe workingfora completelydifferentreason,evenexternal tothe PConwhichtheyare
configured)
