Hi,
Directory listing works and the Python command returns "True"
I found this information (http://support.microsoft.com/kb/937624) which sounded like it might be relevant but then I noticed I already had UAC disabled.
The way I've got 4.2.0 working is with the OMERO.master service set to log on as the domain user that has full access to the network share and local admin rights on the computer. It only starts when set it that way and with the repository in UNC format rather than using the mapped drive's letter. So long as I don't ever use omero admin stop which deletes the service from the list and causes it to start up next time as a local service, the log on as setting sticks, even after rebooting.
Sorry to ask but does the mechanism that checks whether the path exists handle those extra backslashes correctly?
Thanks again.
