Open Microscopy Environment

hi all...

I am running an omero server on a windows server 2008 machine. OMERO itself is workng fine, but I can't start omero.web. I think I followed the setup correctly (installing IIS7, enabling IIS6 + ISAPI WSGI, etc), until

Code: Select all

PS > .\bin\omero web syncmedia
Traceback (most recent call last):
  File "C:\Users\omero\Desktop\OMERO.server-Beta-4.2.2\bin\\omero", line 123, in <module>
    rv = omero.cli.argv()

    os.remove(os.path.abspath(location / 'media' / app))
WindowsError: [Error 5] Access is denied: u'C:\\Users\\omero\\Desktop\\OMERO.server-Beta-4.2.2\\lib\\python\\omeroweb\\media\\webgateway'

I tried on an elevated (admin) prompt and giving access to that folder to everybody without success. Trying to access http://localhost/webadmin gives me a 401.3 Error: 'HTTP Error 401.3 - Unauthorized You do not have permission to view this directory or page because of the access control list (ACL) configuration or encryption settings for this resource on the Web server. ' (got a 401 trying to connect from a distant machine too).

[fake edit]Ha, but setting the whole of the OMERO.server folder open to everyone r/w seems to do the trick and OMERO.web is working (although only a few of the thumbnail are loading?). But that would be bad, I guess 'syncmedia' is to remedy to that...

Anyway, any help is appreciated...

The Windows permissions there certainly are tricky and while I wrote the documentation and tested the IIS7 implementation I don't presume to be an expert. I haven't deployed on Windows Server 2008, all the tests were done with Windows Vista. I do know that the IIS (the actual Windows account name escapes me) must have read, write and execute permissions to at least the directories in question (otherwise all hell will break loose there when trying to execute Python code and the ISAPI wrapper).
