Hello. Using 18.104.22.168. Had to change the password for the administrator on the server, which was also the HFM DCOM ID. Of course things don't work anymore. Tried to just update the ID/password in the HFM DCOM configuration screen but didn't work. Went to the other extreme and did a full new configuration (new database, etc.). Workspace, etc. work fine. But cannot create cluster in HFM, etc.
Changing the admin pwd on the HFM box .... all you had to do was go to component services and change pwds there for all dcom componenets using the said ID.... I have done this about 3 time for HFM & FDM setup.
