[Server-devel] Problems with the School Server and IIAB

[Tony Anderson]

Hi, all

I have been offline for several days. I am just now reading a backlog of 
200 emails.
Please bear with me on this.

I have recommended that IIAB be given a fixed IP from the beginning; 
however, I have not had a chance to look at this problem to determine if 
that is relevant here.
