Just finished a Sametime 8.5.1 installation on SLES 10. The clean install was painless and ran without any issues.

For Sametime 8.5 I wrote my own shellscript to start and stop the different components of the Sametime installation automatically at startup.

In 8.5.1, IBM creates the start/stop scripts during installation. The only thing you have to do is to enable the services in runlevel editor.

I do not know, if this also works in a Windows environment. If anyone has information, please leave a comment.
