Cannot start windows service during startup

Hi
we installed Omero on the windows XP operating system following the "OMERO.server Installation for Microsoft Windows" instructions.
The command prompt gives me this error message at startup:
C:\omero_dist>bin\omero admin start
No descriptor given. Using etc\grid\windefault.xml
[SC] StartService: OpenService FAILED 1060:
The specified service does not exist.
Waiting on startup. Use CTRL-C to exit
.............................Failed to startup after 5 minutes
We are using the folowing packages:
ActivePython-2.5.4.4-win32-x86.msi
Ice-3.3.1-VC8.0.msi
jre-6u16-windows-i586.exe
omero-Beta4.0.3.zip
postgresql-8.4.1-1-windows.exe
Any ideas?
