Re: Exceptions RPC_S_UNKNOWN_IF

Tech-Archive recommends: Fix windows errors by optimizing your registry

I thought you were going down that road too... I did have problems the first
time I ran the servers on a system that had XP SP2 installed, But I have
fixed that issue months ago..

This problem I know has existed before I installed Windows 2003 SP1 on my
server(s), But have ignored it for a while, but since I'm getting closer and
closer to actual release, I'm trying to weed out all of the bugs that I can
find..

Any idea??

For the mean time, I think I have a "work around" that will fix this issue,
(a retry loop) But would like an actual fix... or a reason why? Do you
need to see any other code? or anything?

Thanks,
Weston Fryatt
