You're telling me....I've been fighting this one for a while. problem Is 
I'm not sure when it started because it's so intermittent I might not 
have noticed it for weeks.

I'll take a look at this after lunch and let you know what I find.

Yes it is, and as of this week the client and server are on their own 
switch. I suppose I could start sniffing the network, But I'll have to 
get that all setup.

I"m half tempted to just come in in the middle of the night and reboot 
everything, but I know I shouldn't need to do that and I'd rather 
Identify the problem and know what it was.

Thanks Fred, I"ll let you know what I find out.
