We have had a problem with this when then systemports that BIM server are using is already occupied by other software. this will cause the BIM server to "hang" and remain offline. As far as i know the iss no way to reserve spesific port to BIM server. The problem is report to GS here i n Norway. Hopefully there will be a fix for this.
In the Advanced Settings panel of the BIM Server Preferences Dialog you can set specific port numbers.
Just make sure that if you change the Discovery port then you need to change it also in the Network and Update page of the Work Environment Dialog.
