Hi, Zhang, it's really good to have you back, and right on the case like this!

 On the server and printers stuff, I'd like to meet up with you briefly on-site this week.  Mostly we should activate an INSTR account for you and make sure it's in group GG-Tech-Ray, or equivalently set a password that you will control for the existing semi-generic INSTR account that already belongs to that group.  But also we should discuss the general printing strategies for the classrooms and labs.

(Even without either approach to an admin INSTR account, the server just like the desktops has a this-computertechco privileged user, with the standard school-specific techco password.  That user should be able to manage the printers -- it's just not a domain user so can't do anything about the group-policy-based printer scripts. Also I'm not sure if it can RDC to the server, but if need be you could go to the console physically at the MDF.  But if it's not more urgent, hold off and we'll do one of the INSTR approaches.)

The classroom computer printing to the lab printer is of course just one more ill side-effect of teachers moving  computers around without consulting the tech folks.    If we don't decide to give up on "Location-Based Printing" (with Group-Policy-based script), then one of the necessary but less than obvious things that needs to be changed when moving a computer is the Computer Description field, since the script branches based on this.  I suspect the system is getting too old and cranky to be useful much longer; but with direct TCP/IP printer entries, you still have to do something on each moved computer, so there doesn't seem to be a zero-extra-labor answer.  Let's you-and-me-and-Russ talk over this decision -- it would be nice to have a Ray admin or teacher in on this, but AFAIK there is only one who would be able to follow the tech side of the question and she probably doesn't want to be involved.

  Thanks,

  ==Mitch
