HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
DNS Service
dnsresolver.exe
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices\
DNS Service

W32/SdBot-R connects to an IRC server and joins a particular channel, providing unauthorised access and control of the computer from the IRC channel.
