Hi there, I'm new to condor, and am struggling to setup/administer a small pool of Windows 7 machines.
Could someone give me a few clues please?

So far I have 4 machines with condor installed, and have had some success submitting jobs from a client, and they execute OK on three PCs.

However I have two problems:

1 A general point - All the different executables to be run assume they are run from a particular directory in a  hierarchy - the requirements being different for the different types of executable,
   So I have tried submitting  a windows batch file, which uses pushd to a shared unc path on the submitting machine: like this

 pushd \\mycomputername\MyDirectory 

\\mycomputername\MyDirectory\myExecutable args..

This seems to work on for three machines, but my question is  this going to be scalable when I add more machines to the pool?
 - I have sometimes seen error output from the executables like: 
"No more connections can be made to this remote computer at this time because there are already as many connections as the computer can accept In the error output of the programs."
My question Would this happen more for a bigger pool - being as all the remote executable would have to write to/read from  the same share?
 and would upgrading one of the machines to a windows server help ?
 or is there another way around this?

2 Second question is very specific: 
One of the machines shows the correct LocalCredd value - I've made the Credd permissions very lax, But will  not run jobs - I've looked at its starter Log, it seems to loose communication with the master  (EDI-IAR1), then shutdown.
