I am almost positive that all of my clients are running WSS and MOSS Service Pack 1 and should be installing the WSS and MOSS Infrastructure updates if you haven't already. However, if you haven't installed SP1 please be aware that support for systems without SP1 will end on January 13th, 2009. So in around 6 weeks.

After January 13th, 2009 support can only be provided for systems which have SP1 installed!
