If you get error 1902 when you try to start the raysat satellite service, it’s probably because there is no entry for the service in the services file.
C:\Program Files\Autodesk\Softimage 2011\Application\bin>raysatsi2011_3_8_1_31server.exe /install

raysatsi2011_3_8_1_31server error: (1092) RaySatsi2011_3_8_1_31 Server failed to start
Use a text editor to edit C:\Windows\system32\drivers\etc\services and add an entry that looks like this:
mi-raysatsi2011_3_8_1_31 7004/tcp #
I’ve used port 7004 in this example, but you’ll have to check that no other service is using that port.
In a recent support case, a customer reported he was getting an error that looked like this:
' INFO : Rendering frame 123 (62.5% done)
' FATAL : DB 0.14 fatal 041052: accessing unknown tag 0x41d
' FATAL : mental ray has encountered a fatal error condition.
' It has been disabled for the rest of this XSI session.
' Please save your work and and contact Softimage support (email@example.com).
Sometimes “accessing unknown tag” errors can happen when you run out of memory. Other times, “accessing unknown tag” errors can indicate that something is missing in the scene database created by mental ray. Everything in the scene database has a tag, including shaders and light profiles. Shaders use the tags to reference objects, so if some input to a shader is missing, you would get the “unknown tag” error.
In this particular case, the customer was able to resolve the problem by removing all unused materials and image clips from the scene.
