Hi Guys Can anyone help me. I am running XP home on a 2.8 intel with 2 gig of ram masses of hard disk space etc. It has always run perfect apart from this last few weeks. It keeps randomly rebooting and according to the event viewer the error is as follows. The server {F4524160-9145-49C9-8810-46CBC1EA0021} did not register with DCOM within the required timeout. I do have a another machine which is networked to the main computer and I suspect it is something to do with that but I don't realy know. Has anyone any ideas please.
