Does anybody have ANY idea about how to fix? Is this a permissions thing?
Thanks in advance!

So... I am a complete idiot!. I spent a DAY trying to figure out the problem. In the end, I had not installed SQL2k5. I had installed the tools, but they were connecting to SQL 2k.

thanks,

Dork|||Glad to hear you "fixed" the problem!|||
