JSI Tip 7760. How can I determine if Dynamic DNS Registration is enabled on a Windows XP client?

I have scripted DynDNS.bat to determine if Dynamic DNS Registration is enabled on a Windows XP client.

The syntax for using DynDNS.bat is:

Call DynDNS YesNoX

Where YesNoX is a call directed environment variable that will contain a X if the client is NOT a Windows XP computer, a Y if Dynamic DNS Registration is enabled, and a N if Dynamic DNS Registration is NOT enabled.

DynDNS.bat contains:

@echo offsetlocal ENABLEDELAYEDEXPANSIONif {%1}=={} goto syntaxset DNSREG=Nif not exist "%SystemRoot%System32reg.exe" goto notxpset XP=reg.exe query "HKLMSOFTWAREMicrosoftWindows NTCurrentVersion"for /f "Tokens=1-3" %%u in ('%XP%^|Find "5.1"^|Find /i "CurrentVersion"') do ( if /i "%%u" NEQ "CurrentVersion" goto notxp)for /f "Tokens=3 Delims=[] " %%i in ('ping -n 1 "%computername%" ^|find /i "Pinging"') do ( set IP=%%i)if not defined IP goto errorset IP=%IP: =%set int1=reg.exe query HKLMSYSTEMCurrentControlSetServicesTcpipParametersInterfacesfor /f "Tokens=*" %%a in ('%int1%^|Find "{"') do ( set ikey=%%a if "!DNSREG!"
