I did not find the article I thought I recalled seeing. Much can probably be gleaned indirectly from support articles such as these: http://support.microsoft.com/default.aspx?scid=kb;en-us;159298 http://support.microsoft.com/default.aspx?scid=kb;en-us;325930 http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnanchor/html/rpcank.asp hmm . . may be we can get explicit information with this one above In fact, the whole site looks like a searchable gold mine: http://msdn.microsoft.com/library/default.asp I'm not entirely sure what you need so here are some others. They are probably less helpful: http://www.microsoft.com/com/wpaper/dcomfw.asp?SD=GN&LN=EN-US&gssnb=1 http://support.microsoft.com/default.aspx?kbid=154596 http://support.microsoft.com/default.aspx?scid=kb;en-us;832017 http://support.microsoft.com/default.aspx?scid=kb;en-us;129143 http://support.microsoft.com/default.aspx?scid=kb;en-us;197814 http://support.microsoft.com/default.aspx?scid=kb;en-us;96781 I hope it helps - John On Thu, 2004-04-01 at 18:34, Ian Latter wrote: > Hello John, > > > Thank you for this report. > > The RPC conntrack helper was written to support ONC RPC - > typically used on Unix hosts - where as Windows uses DCE RPC. > When I last looked at that module, I tried to find technical > information on the differences of the two, and was unable to > find any - but had the impression from what I could find that the > two weren't compatible. > > Whether or not the module recieves valid/invalid traffic, it shouldn't > crash - and I want to fix that. > > However, if you have access to documentation on DCE RPC > protocol/standards then please forward that/them through, as any > such documentation would be useful for broadening support. > > On the report details; what was typically on both sides of the > filtering engine (Windows 2000 Server on the server side and > Windows XP Pro on the client side?) and do you have any idea > what type of activity was performed at the time of the crash? > (Ie, is there any way that I can repeat the fault directly?) > > > > Thanks again for your time and info, John. > > > > > > ----- Original Message ----- > >From: "John A.
