Hi Alll,
I have an issue with BI Presentation Services Can anyone help. My issue is that when I try to start the services the presentation one doesn't start. I have tried looking at the log file it states but it just says Starting Process.......
I tried starting it in the EM Console and All I can see is that it givesme a Wrapper Context error and nothing is.
Any one have any solution to this? Please help.

Just in case check loopback configration at the /etc/hosts file must be modified to contain the following entries:
127.0.0.1 hostname.domainname hostname
127.0.0.1 localhost.localdomain localhost
After doing so, you can check that the host name resolves to the loopback IP using command:
/bin/ping hostname.domainname
