change hostname in document link

Hello,

We are on BI 4.1 SP1 on Win2008R2.

We moved from hosta to hostb.

In BI LaunchPad, when I right click the report and choose "Document Link" it open a link.

I still see the old hostname, which is hosta.

How can I change it. There must some global setting so all link picks up new hostname.

Please advice if anyone has come across this issue.

Thank you.

Regards,

SS
