This is just something I've come across whilst putting up a network in my house. I've just, for the first time, installed my LAN drivers for my built in Rhine II Fast Ethernet Adaptor (ABIT KV7 mobo). So after that I plugged it via a cat5 ethernet cable into the 10/100 HUB (which at the moment isn't connected to anything other than an XBOX until i get hold of some 15m cabling to connect it to another HUB). Anywho, whilst looking in the event viewer, under applications, I came across the message : The COM+ Event System detected a bad return code during its internal processing. HRESULT was C0000005 from line 44 of d:\qxp_slp\com\com1x\src\events\tier1\eventsystemobj.cpp. Please contact Microsoft Product Support Services to report this error. Now the strange thing is this message repeats itself each time I reboot until I either A) Disable the Rhine II Ethernet Adaptor OR B)Unplug the cable from my PC....then the error message vanishes. I've googled the search and I came up with a few sites. The most frequent pointed to : http://www.eventid.net/display.asp?eventid=4609&eventno=1993&source=EventSystem&phase=1 Only problem is Local Security Policies doesn't exist, either because I'm running XP Home or the fact my XP is oem. Of course I have yet to try the LAN with other PC's but I don't know, in my past endeavors a c0000005 error is usually not such a nice thing.
