Question

how do I find out what rwcrmwc117.ops.asp.att.net is or means???

Answer 1

Where did you get it? That would help.
Anyway, it looks like it is the name of a particular server used by AT&T on their customer network.

By the way you need to confirm your email address, that's what Yahoo says.
