Then, it's something within SP2 itself I assume (which winmsgr uses to connect to SIP).... Did you try to remove winmsgr 4.7.3000 first (in the hope it also removes the "SIP-modules" (sorry, don't have a better name for it))? Because often, when you install an older product, newer DLL's and such aren't downgraded...

(note to others: do not use this method to remove windows messenger if you aren't going to install another windows messenger version!!! This is not meant to "disable" windows messenger!!! instead read "CookieRevised's reply to I am about to rip my hair out over MS Messanger" for that)

hi CookieRevised ... thanks for the tip,
unfortunately, it doesn't work.
I have confirmed that the problem is related to changes in the underlying RPC system in XP SP2, not just WM 4.7, and that  others with the same problem say that there is no solution at the moment.

cheers!.
