I found a good page using Google:
http://en.wikipedia.org/wiki/Lightweight_Directory_Access_Protocol. However, if you don't know what LDAP is, you most likely don't want it. As I suggested yesterday, remove the LDAP settings which you added and disable it.
While the LDAP settings in your configuration are wrong, this does not solve your original problem of the python processes not running. One discrepancy I saw was an error in the screenshot of the logs that D:\OMERO\Image did not exist. But in your "omero config get" output, the directory is C:\OMERO. I'm not sure where (or if) D:\OMERO exists (or if this is related to OMERO, since the log just mentions a service called "Server"), but it might be worth making sure that D:\OMERO and D:\OMERO\Image exist and are directories (folders).
Given the difficulty of diagnosing what's going wrong using the forum, if you you have any IT support within your institution who could assist you directly with investigating the cause of your problems, this is likely to result in much faster resolution of the problems you've encountered setting up OMERO.
