RPCSS Error

Upon booting my WIN95 machine, I always get the error message “RPCSS: This program has performed an illegal operation”. I always just click “OK” and the message/error goes away, the machine boots and then runs normally. The “error” seems benign — it doesn’t affect my system at all. I checked the MS Knowledgebase, but with absolutely no luck. I even searched the Web — no luck.

Any ideas about this? Thanks!
