I'm having a weird issue where if I login as any user (admin, end user, domain admin) onto this one XP workstation, it shows the background screen for quite sometime before explorer actually comes up. I've found that killing the svchost.exe associated with RPC will finally cause windows to come up. If I login to safe mode, it does not have this issue.
I'm also seeing some DCOM errors in the event log: The server did not register with DCOM within the required timeout
I'm about ready to re-ghost this machine as I have no clue what else to do, but I heard about something very similar happening on another workstation yesterday... so I'd really like to resolve this.
